Question

Name the final product formed during the ammonalysis of $C{H}_{3}I$.

Answer 1

$C{H}_3-I+N{H}_3⟶\underset{\text{methyl amine}}{C{H}_3-N{H}_2}+H-I$

This reaction doesn't stop here, the reaction proceeds further until all the hydrogen atoms from the ammonia are not replaced by an alkyl group.

$C{H}_3-N{H}_2+C{H}_{3}I\to \underset{\text{dimethyl amine}}{(C{H}_3{)}_{2}NH}+HI$

$(C{H}_3{)}_{2}NH+C{H}_{3}I\to \underset{\text{trimethyl amine}}{(C{H}_3{)}_{3}N}+HI$

$(C{H}_3{)}_{3}N+C{H}_{3}I\to \underset{\text{Quarternary ammonium salt}}{(C{H}_3{)}_4{N}^{+}{I}^{-}}$

• Ammonia acts as a solvent in this reaction.
• Thus, the final product of the reaction is Quarternary ammonium salt.
