Q.
The correct order for homolytic bond dissociation energies. $(\mathrm{\Delta}H$in kcal/mol) for $CH_{4}(A),C_{2}H_{6}(B)$ and $CH_{3}Br(C)$, under identical experimental conditions
A) C>B>A
B) B>C>A
C) C>A>B
D) A>B>C
Explanation
(b)
The order of homolytic bond dissociation energies of $CH_{4},\ C_{2}H_{6}\$and $CH_{3}Br$ is as
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ CH_{4} > C_{2}H_{6} > CH_{3}Br$
$\mathrm{\Delta}$H (kcal/mol) 105 100 70
