Among all the HX compounds , only HBr reacts with `CH_3CH=CH_2` in presence of peroxide according to anti - Markownikoff's rule. This is because, in case of HBr, between the third and fourth steps
`(CH_3-CH=CH_2+BrtoCH_3CHCH_2Br and CH_3overset(.)CHCH_2Br+H-BrtoCH_3CH_2CH_2Br+overset(.)Br)`

A

the thired step is exothermic while the fourth step is endothermic

B

both the steps are exothermic

C

the third step is endothrmic while the fourth step is exothermic

D

both the steps are endothermic
