Resources for learning Chemistry

Based on various other Stack exchange site (Mandarin Chinese, Russian and German), we adapt this project here for chemistry, since it's a great idea to have all kinds of resources in one place.

This is a specifically created Community Wiki which gathers resources for learning Chemistry. The lists are a community maintained project, hence everybody with more than 100 reputation points can contribute edits to the appropriate sections. If you feel something is missing, just fill it in. To avoid multiple answers for similar branches, we decided on a general outline, which is locked, i.e. no new answers can be added.
If you have concerns or questions, you can discuss this list on its parent meta post. If they are of a more general concern, you can also post a new question on chemistry.meta.se. This procedure is used, so the comment section here does not become too overcrowded. If you do choose the second option, please leave the link to it in the comments to this post.

Organization

• Answers have a type of resource each.
• If possible, state whether the material is directed towards a beginner, intermediate or an advanced audience.
• Do not include links that lead to illegal content or sites that host such content. If you see any, please flag for moderator attention and choose "other" so you can point us to the content. We'll delete it as soon as we see the flag. (You can of course also delete it yourself. If you do, please flag it anyway, so that we are aware of it. In this case it is crucial you fill in the edit summary with something like: Removed link to illegal content.)
• Both free and commercial resources are allowed, but make sure to include a note if they are the latter. Remember the rules about self-promotion. Include also if registration is required.
• Include links to the sites only, don't post images, they would take too much space.
• Add the resources in alphabetical order so they're easier to find.
• For the resources, a short summary is very much appreciated.

If you have questions about these guidelines, please head to meta to make yourself heard. The above points are not set in stone and might change in the future.

Alphabetical Index

• (Text)Books: All books that teach you chemistry with theory and exercises. The subcategories are:
1. General Chemistry
2. Inorganic, Organic and Physical Chemistry
3. Analytical Chemistry, Biochemistry and Chemical Biology, Chemical Engineering, Computational and Quantum Chemistry, Theoretical Chemistry
You can add any subcategory to this post if it is missing.
• Online courses and Websites: Free or paid services online that teach you chemistry through lessons as well as sites that give help for learning chemistry. They give material, tips, hints, and various help for self-learners or regular students.
• Software: This can be any software ranging from plugins for the browser over mobile apps up to standalone applications for the computer. Pure 2D or 3D visualization programs as well as quantum chemistry programs might not fit in this category, as they are not primarily focused on teaching chemistry.
• Video Resources & TV: Video resources which help learning chemistry.
• References about Nomenclature: Successful communication requires an agreed set of definitions compiled as nomenclature. An example for such compilations are IUPAC's Color Books, named by the color of their book cover.

Currently those are all categories. If you think, that a new one should be added, please submit an answer in the corresponding meta thread. (A comment is probably not sufficient, as it does "bump" the question on the active tab.

• For Organic chemistry I really like "Organic Chemistry" by Brown, Iverson, Anslyn and Foote

• Umm...Paula Bruice would be a good book for beginners..to get the basics clear..and for further reading Peter Sykes is also good. Jan 12 '20 at 16:45
• I found McQuarrie's Quantum Chemistry to be very helpful for quantum mechanics. Especially the "math chapters", which reviewed pertinent math techniques before they are required for each quantum topic. Aug 15 '21 at 23:17

Video Resources (online)

• The University of Nottingham's Periodic Videos
The periodic table of videos includes introductions to all elements. The molecular videos section focuses on interesting chemical reactions. Apart from having quite some entertaining value, they visualise a lot of reactions that can only safely be carried out in a laboratory environment. The videos are hosted on their YouTube channel.

Khan Academy is a site, which is explaining many different subjects to all who are eager to learn. Those subjects are explained through video lessons on youtube, on which the speaker uses a virtual blackboard to draw and clarify the explanations for a deeper understanding. As those videos cover basic theories, it is probably more helpful for the beginner as for the advanced student. There are two channels for chemistry:

Did you know that everything is made out of chemicals? Chemistry is the study of matter: its composition, properties, and reactivity. This material roughly covers a first-year high school or college course, and a good understanding of algebra is helpful.

• Khan Academy - Organic Chemistry
Topics covered in college organic chemistry course are explained. Basic understanding of basic high school or college chemistry assumed (although there is some review).

• Organic Chemistry 1 by University of New Orleans
This is the first semester of sophomore Organic Chemistry.This course completes most chemistry requirements for pre-professional degree programs and science degrees. This course will cover the introduction of basic fundamental topics of organic chemistry. Specifically the structure-activity relationship and spectroscopy of organic functional groups will be investigated. Starting with simple organic models, we will cover structures of organic chemicals from basic connectivity to three- dimensional spatial alignments. Nomenclature and spectroscopy of the different groups will be covered along with reactivity of those groups.

• Organic Chemistry 2 by University of New Orleans
This is the second semester of sophomore Organic Chemistry. This course completes most chemistry requirements for pre-professional degree programs and science degrees. This course will cover the reactions, mechanisms and properties of various functional groups including dienes, arenes, carbonyls, carboxylic acid and their derivatives, phenols, amines as well as biochemicals such as carbohydrates, lipids, amino acids and proteins.

• General Organic Chemistry 2 Course by Arizona State University
This is the complete set materials used in the second semester of Organic Chemistry. It includes home works, video lectures, notes, exams, etc.

• Chemistry Courses by University of Massachusetts - Boston

• “Organic Chemistry – Structure and Reactivity” by UC Berkeley professor Peter C. Vollhardt
An Excellent Resource for Organic Chemistry. It is different from other courses, in the manner the of approach to the topic.

• Organic Reactions and Pharmaceuticals by Professor Hardinger, UCLA
The lectures are lot more exciting than others due to the method of teaching of the professor.Organic Reactions and Pharmaceuticals is a class that provides an in-depth analysis of organic reactions, nucleophilic and electrophilic substitutions and additions; electrophilic aromatic substitutions, carbonyl reactions, catalysis, molecular basis of drug action, and organic chemistry of pharmaceuticals.

• UC Irvine OpenCourseWare
This is mother of all resources. OpenChem by UCI offers a course on each and every aspect of chemistry. It has 6 different courses for organic chemistry whose levels vary from undergraduate to graduate.

• The youtube channel of the Australian and New Zealand Society for Magnetic Resonance
Presented briefly by Kwan et al. in the Journal of Chemical Education, basic and advanced principles of NMR / MRI and EPR are lectured.

• MIT 5.60 Thermodynamics and Kinetics, Spring 2008
The above course is available as a part of MIT OCW. Links in the description of video lectures includes lecture notes, readings, exams and course materials available for download. Covers a basic to intermediate introduction to thermodynamics and kinetics at the undergraduate level.

• TMP Chem

Television

• Uranium- Twisting the Dragon's Tail
Host and physicist Dr. Derek Muller unlocks the mysteries of uranium, one of the Earth's most controversial elements. Born from the collapse of a star, uranium has brought hope, progress and destruction. It has revolutionized society, from medicine to warfare. It is an element that has profoundly shaped the past, will change the future and will exist long after humans have left the Earth.

Online Courses

• Chemistry LibreTexts
This collection was formerly known as UC Davis' ChemWiki: The Dynamic Chemistry Hypertext. It is a collaborative approach toward chemistry education where an Open Access textbook environment is constantly being written and re-written by students and faculty members resulting in a free Chemistry textbook to supplant conventional paper-based books.

• Jim Clark's Chemguide
An in-depth overview of many areas of basic chemistry, including organic, inorganic, physical, and instrumental. Forgoes mathematical treatments of chemistry in favor of teaching an intuitive understanding for how chemical systems behave. Targeted at UK A-level students, but useful for anyone who wants to shore up their fundamentals.

• Virtual Textbook of Organic Chemistry
A very useful introduction to principles in organic chemistry and the reactions of common functional groups.

Websites

• IUPAC Compendium of Chemical Terminology - the Gold Book
A concise compendium of the most common terminology that is used in chemical and related sciences.

• NIST Chemistry WebBook
A searchable database for standard reference data of chemical compounds by the National Institute of Standards and Technologies.

• Symmetry@Otterbein

• A Hypertext Book of Crystallographic Space Group Diagrams and Tables
The Space group diagrams you find in the in the International Tables of Crystallography. It equally considers standard settings (e.g., $$P2_1/c$$) and alternatives like $$P2_1/a$$, $$P2_1/n$$, $$B2_1/a$$, $$B2_1/d$$ -- all of the filed under #14.

• Online Dictionary of Crystallography
The dictionary is provided by the International Union of Crystallography (IUCr). It is a curated glossary about the more frequently met crystallographic concepts.

• Organic Chemistry Lab Techniques
An illustrated collection of basic techniques met in the organic chemistry lab. The content naturally shows some overlaps with / complements to print primers like the one by Zubrick.

• Organic Chemistry Data & Info
A site of general interest about chemical and reaction data, cross-link to literature references (like the Hans Reich collection) useful for the chemist in the lab as well as educators/students. Moderated by the Division of Organic Chemistry of the American Chemical Society.

• Is there a clean difference between an online course a website, or is it somewhat fuzzy? Sep 15 '15 at 21:54
• For me, the online courses are a special subset of websites that are explicitly for teaching conceptual stuff and not only for giving some information. E.g., the mentioned Goldbook and the Webbook both give information from which you can learn, but they are not teaching like what you'd expect from a school lesson. And then there are sites like Khan Acadamy on youtube, which besides other subjects is about teaching chemistry and should be classified as an online course. But I guess you are right, when saying it can be quite fuzzy. (Please ask about such things in the meta thread next time.) Sep 16 '15 at 0:57
• Another great website is the eBook Principles of General Chemistry

Books about Biochemistry and Chemical Biology

• The probably most comprehensive reference for chemical engineering is the McGraw-Hill Chemical Engineering Series, which contains more than you should know as a student. After all a strong knowledge in all areas of chemistry is necessary. As an engineer, and a chemist especially, if you are looking for sizing operations, you'll need to think about details, which are not in the books unfortunately.
For the related question, see: What are introductory level books on chemical engineering?

• The Visual Encyclopedia of Chemical Engineering is a project hosted by the Department of Chemical Engineering, University of Michigan. By text, illustration, and video, typical applications of devices and processes, their advantages and disadvantages are presented. Equally, means to monitor processes are shown and literature references (pointing e.g. to Perry's Chemical Engineering Handbook) provided.
