Vedclass · Answer

(D) The preparation of butanenitrile $(CH_3CH_2CH_2CN)$ involves the nucleophilic substitution reaction of an alkyl halide with potassium cyanide $(KCN)$.To obtain a four-carbon nitrile, we need a three-carbon alkyl halide.$CH_3-CH_2-CH_2-Cl + KCN \xrightarrow{S_N2} CH_3-CH_2-CH_2-CN + KCl$.Thus, propyl chloride $(CH_3CH_2CH_2Cl)$ reacts with $KCN$ to form butanenitrile.

Butanenitrile can be prepared by heating $KCN$ with which of the following?
