The correct order for homolytic bond dis...

The correct order for homolytic bond dissociation energies (`Delta H` in kcal/mol) for `CH_(4)(A), C_(2)H_(6)(B)` and `CH_(3)Br(C)` is

A

`C gt B gt A`

B

`B gt A gt C`

C

`C gt A gt B `

D

`A gt B gt C`

Text Solution

Verified by Experts

The correct Answer is:
B
`CH_(3)` has only 3 homolytic bonds dissociation energy will be lowest among all, because in `CH_(4)` the number of bonds are 4 and ethane ) ( `C_(2)H_(6)`) has highest number of bonds. Hence, the correct order is `C_(2) H_(6) gt CH_(4) gt CH_(3) Br`
`B gt A gt C`
