Heterolytic bond dissociation energy of `C-Br` bond is minimum forA. `CH_(3)Br`B. `CH_(3)CH_(2)Br`C. `(CH_(3))_(2)CHBR`D. `(CH_(3))_(3)CBr`

Answer» Correct Answer - D
This bonds dissociation energy is the amount of energy that must be supplied to convert a mole of alkyl bromide into carbocations and bromide ions:
`R-Br-gt R^(+)+Br^(-)`
The order of relative stability of carbocations is as follows:
`3^(@) gt 2^(@) gt 1^(@) gt overset(+)CH_(3)`
because the more stable the carbocation, the lesser the enrgy required to form the carbocation.
