Question
Butanenitrile may be prepared by heating ______.
Options
propanol with KCN
butanol with KCN
n-butyl chloride with KCN
n-propyl chloride with KCN

Solution
Butanenitrile may be prepared by heating n-propyl chloride with KCN.
Explanation:
Preparation of butanenitrile
\[\ce{CH3 - CH2 CH2Cl + KCN ->[\Delta] CH3 - CH2 - CH2CN + KCl}\]
So, butanenitrile may be prepared by heating Propyl Chloride with \[\ce{KCN}\].
