π-Bond Dissociation Energies: C-C, C-N, and C-O.

Single, double, and triple bond dissociation energies are useful quantities, but students and practicing chemists commonly do not know representative values or how they are obtained. In this paper, select π-bond energies are provided and general methods for their determination are discussed. Relationships between heats of hydrogenation, bond dissociation energies, and π-bond strengths are also addressed.
