Vedclass · Accepted Answer

Butan$-2-$one $\xrightarrow{HCN/OH^-}$ $2-$hydroxy$-2-$methylbutanenitrile

Vedclass · Answer

(B) : The reaction of but$-1-$ene with $HCl$ in the presence of $H_2O_2$ (peroxide) does not follow anti-Markovnikov addition because peroxide effect is only applicable for $HBr$. Thus,it gives $2-$chlorobutane,not $1-$chlorobutane. This is incorrect.$B$: The reaction of butan$-2-$one with $HCN$ in the presence of $OH^-$ is a nucleophilic addition reaction forming a cyanohydrin. The product is $2-$hydroxy$-2-$methylbutanenitrile. This is correct.$C$: The reaction of cyclohexene with $Cl_2$ in the presence of heat (or light) typically leads to allylic substitution,not addition. Addition of $Cl_2$ to cyclohexene occurs at room temperature to give trans$-1,2-$dichlorocyclohexane. This is incorrect.Therefore,only option $B$ is correctly matched.
