Solution

The correct option is A diazotisation
Diazonium ions are prepared by diazotisation, a procedure in which a primary aromatic amine $(A r N H_{2})$ is treated with a source of nitrous acid $(H N O_{2})$ . Typically this involves adding sodium nitrite $(N a N O_{2})$ to an aqueous acidic solution containing the amine.

Q. The conversion of primary aromatic amines into diazonium salts is known as ___________.

Assertion (A): Both aromatic and aliphatic primary amines produce stable diazonium salts on diazotization

Reason (R): Aromatic diazonium salt exhibit resonance

Q. Diazonium salts of aliphatic amines are more stable than those of aromatic amines.
If this is true enter 1, if false enter 0.

Why cannot aromatic primary amines be prepared by Gabriel phthalimide synthesis?

Account for the following

(ii) Ethylamine is soluble in water whereas aniline is not

(iii) Methyl amine in water reacts with ferric chloride to precipitate hydrated ferric oxide

(iv) Although amino group is o- and p- directing in aromatic electrophilic substitution, aniline on nitration gives a substantial amount of m-nitroaniline

(v) Aniline does not undergo Friedel Crafts reaction

(vi) Diazonium salts of aromatic amines are more stable than those of aliphatic amines

(vii) Gabriel phthalimide synthesis is preferred for synthesising primary amines
