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.
