... The idea that acids are solutions containing a lot of “H+” and bases are solutions containing a lot of “OH-” is not very useful in organic chemistry • Instead, Brønsted–Lowry theory defines acids and bases by their role in reactions that transfer protons (H+) between donors and acceptors ...

... The resonance energy stabilization in benzene amounts to 30 kcal/mol. This can be calculated experimentally by considering the -orbital energies ("'s & 's"), or measured experimentally via the enthalpies of hydrogenation. In molecules such as cyclooctatetraene, a fully delocalized -electron conf ...
