Question

what is the correct order for homolytic bond dissociation energies

(A)CH4
(B)C2H6
(C)CH3Br

Answer 1

CH_{3}Br has only 3 homolytic bonds, so for this homolytic bond dissociation energy will be lowest among all, because in CH_{4} the numbers of bonds is 4 and ethane C_{2}H_{6} has the highest number of bonds of all higher mentioned compounds.
