Match the reactions given in Column I with the statements given in Column II

 

• Ammonolysis,

It is the reaction in which an alkyl or benzyl halide reacts with ammonia via nucleophilic substitution reaction.

$\mathrm{R}-\mathrm{X}+{\mathrm{NH}}_3\to \mathrm{R}-{\mathrm{NH}}_3{{}^{+}\mathrm{X}}^{-}$

• Gabriel phthalimide synthesis,

The Gabriel Synthesis of amines is the reaction in which primary halides are converted into primary amines via SN² reaction.

It is used for the preparation of primary amines only.

• Hoffmann Bromamide reaction,

This reaction is used for the conversion of a primary amide to a primary amine with one less carbon atom.

${\mathrm{CH}}_3{\mathrm{CONH}}_2+4\mathrm{KOH}+{\mathrm{Br}}_2\to {\mathrm{CH}}_3{\mathrm{NH}}_2+{\mathrm{Na}}_2{\mathrm{CO}}_3+2\mathrm{KBr}+2{\mathrm{H}}_2\mathrm{O}$

• Carbylamine reaction,

It is used to test primary amines by converting it into isocyanide.

${\mathrm{RNH}}_2+{\mathrm{CHCl}}_3+3\mathrm{KOH}\stackrel{∆}{\to }\mathrm{RNC}+3\mathrm{KCl}+3{\mathrm{H}}_2\mathrm{O}$

Thus, from above it is clear that the correct matching is: a-4, b-3, c-1, d-2.
