Solution
The correct option is C To remove acidic impurities Alkyl and benzyl halides on reaction with an alcoholic solution of ammonia (nucleophile) undergoes nucleophilic substitution of the halogen atom by the amino group (−NH2). This process is known as ammonolysis.
General reaction is as follows: NH3+R−X→RNH+3X−
Then, the substituted ammonium salt reacts with strong base to give free amine.
General reaction is as follows: RNH+3X−+NaOH→RNH2+NaX+H2O
Thus, it removes the acidic impurities as salt 'NaX'
