Vedclass · Answer

(A) Step $1$: Anti-Markovnikov addition of $HBr$ to $1$-methylcyclopentene in the presence of benzoyl peroxide gives $1$-bromo-$2$-methylcyclopentane.Step $2$: Nucleophilic substitution $(S_N2)$ of the bromide with $KCN$ yields $1$-cyano-$2$-methylcyclopentane.Step $3$: Reduction of the nitrile group $(-CN)$ using $Na(Hg)/C_2H_5OH$ (Mendius reduction) converts it into a primary amine $(-CH_2NH_2)$.Thus,the final product $P$ is $1$-methyl-$2$-(aminomethyl)cyclopentane.

Predict the major product $P$ in the following sequence of reactions$-$
$(i)$ $HBr$,benzoyl peroxide
(ii) $KCN$
(iii) $Na(Hg)/C_2H_5OH$
