List-I |
List-II |
|
(A) Gatterman's reaction |
(III) Aryl Halide |
|
(B) Carbylamine reaction |
(I) Alkyl isocyanide |
|
(C) Hoffmann bromamide reaction |
(IV) Primary amine |
|
(D) Coupling reaction |
(II) Azo Compound |
(A) Gattermann Reaction → (III) Aryl Halide
In Gattermann reaction, a diazonium salt is converted into aryl chloride or aryl bromide using HCl/HBr and copper powder. Hence product is aryl halide.
(B) Carbylamine Reaction → (I) Alkyl Isocyanide
Primary amines when heated with chloroform and alcoholic KOH give isocyanides (foul smell). Hence alkyl isocyanide.
(C) Hoffmann Bromamide Reaction → (IV) Primary Amine
Amide reacts with bromine and KOH to form a primary amine with one carbon less.
(D) Coupling Reaction → (II) Azo Compound
Diazonium salts react with phenols or amines to form azo dyes (–N=N– linkage).
