Tags

A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.

For questions about determining the paramagnetism, diamagnetism, etc. of chemical species and other chemical applications of magnetism. Note that questions oriented towards physical aspects of electro…

100 questions
Also known as cis/trans isomerism, configurational isomerism, or E/Z isomerism when referring to alkenes.
99 questions
for questions about phenols, their synthesis, analysis, properties and more. Do not use the 'alcohols' tag for phenols due to the differences between the two classes.
97 questions
For questions about the process of distillation. For the distillation process used in metal refining, also use the [metallurgy] tag.
94 questions
macromolecular biological catalysts that alter the rate of a reaction. Use this tag for question regarding enzyme kinetics, classification and action.
93 questions

92 questions
Questions about any process which makes water more acceptable for an end use.
92 questions
on E1, E2, E1cb, or any other type of elimination reaction.
The systematic discussion of molecular symmetry is known as group theory. Group theory is a systematic way of describing the symmetry of molecules using concepts/rules borrowed from mathematics. This…
92 questions
for questions about amino acids, both natural and non-natural ones. It should only be applied to questions about the monomers. For peptides and proteins, use the proteins tag instead.
For questions regarding the chemical processes or chemicals involved in distinguishable smells
89 questions
The adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface.
88 questions
For questions regarding chemicals and chemical processes that act on and interact within environmental systems.
87 questions
Questions discussing explosive nature of chemicals. Also, consider using the safety tag.
86 questions
a type of angular momentum which is intrinsic to atomic and sub-atomic particles. Electrons in orbitals can be either spin paired or spin unpaired which influences the magnetic properties of t…
84 questions
Chemical processes and theories being used in practical and experimental applications.
83 questions
For questions involving selectivity as to where a functional group reacts.
