I agree in part with Mithoron and MaxW's comments: these are different molecules, not even sharing a mutual atom (e.g. C-O vs C-C), so direct comparison is restricted. However, Pauling's concept of electronegativity does explain why, in general, the heteronuclear A-B bond is stronger than the average of the homonuclear A-A and B-B bonds. the difference in ...

They're for the entire bond (so for a triple bond, all 3). From Wikipedia, it can be defined as The standard enthalpy change when [a bond, be it single, double, or triple] is cleaved by homolysis to give fragments A and B, which are usually radical species So you get two fragments as your final state.

This question has a few different parts to it. Part 1 - what's that peak at 3.6ppm? Well, it's not the -OH peak. The peak at 3.6 is from the CH(OH). Part 2 - where is the -OH peak if that isn't it at 3.6ppm? Peaks from labile protons are frequently not observed, and have variable chemical shifts, unless great care is taken in sample preparation. This ...

The unsaturated regions are electron-rich and typically allow for electrophilic attack, such as by halogens or protons. Saturated hydrocarbons usually react only with radicals (radical halogenation). C-H activation is often hard in saturated hydrocarbons. While double and triple bonds are stronger than a single bond when looking at complete cleavage of a ...

When a substance is made of molecules, these molecules are made of atoms being strongly attached to one another. But a given molecule is not attached to its neighbor by strong bonds. On the contrary, they are attached by so-called van der Waals forces, which are rather weak. If you heat such a substance, the van der Waals forces are easy to destroy, and the ...

Both are correct: for $\ce{Cl-}$, the inner set of electrons would be implicit, as $\ce{Cl}$ has 17 electrons. The point of drawing these orbital diagrams, especially in a molecular context, is to show the nature of bonds and to show how the octet/duplet rules are being followed. If you have difficulties in using the second diagram (finding it harder to ...

A possible real-world example of directional force use may be apparent from the commercial application of so-called magnetizers (see discussion here). I once experimented with a small inexpensive one and it appears to accelerate select reactions. A commercial example for reducing the amount of chlorinating agent required in public swimming pools in ...
