Vedclass · Answer

(C) The anti-Markovnikov addition (peroxide effect) is only observed with $HBr$ in the presence of organic peroxides. This is because the $H-Cl$ bond is very strong $(431 \ kJ \ mol^{-1})$,and the enthalpy change for the homolytic cleavage of $HCl$ by free radicals is endothermic,making the reaction energetically unfavorable. In contrast,the $H-Br$ bond is weaker,allowing for the formation of bromine free radicals which facilitate the anti-Markovnikov addition.

$HCl$ does not follow the anti-Markovnikov rule because...
