Vedclass · Answer

(B) The addition of $HBr$ to unsymmetrical alkenes follows Markownikoff's rule in the absence of peroxides,leading to the formation of the more stable carbocation intermediate.In the presence of peroxides $(R_2O_2)$,the reaction proceeds via a free radical mechanism,which results in anti-Markownikoff addition.For example,the reaction of propene with $HBr$ in the presence of peroxide yields $1$-bromopropane instead of $2$-bromopropane.Therefore,the correct option is $(B)$.
