Question

What is the type of amine obtained from the ammonolysis of alkyl halides?

• A. Primary
• B. Primary and secondary
• C. Secondary and tertiary
• D. Primary, secondary and tertiary

Answer 1

The correct option is D Primary, secondary and tertiary

When an alcoholic solution of ammonia is heated with alkyl halides, a mixture of all three types of amines, i.e., primary, secondary and tertiary amines are formed along with a quaternary ammonium salt.
General reaction is as follows:
$N{H}_3+R-X\to RN{H}_3^{+}{X}^{-}$

Then, the substituted ammonium salt reacts with strong base to give free amine.

General reaction is as follows:
$RN{H}_3^{+}{X}^{-}+NaOH\to RN{H}_2+NaX+H_{2}O$
