Give reasons for any 3 of the following observations:

(a) Aniline does not undergo Friedel-Craft’s alkylation.

(b) Primary amines have higher boiling point than tertiary amines.(c) Acetylation of Aniline reduces the activation effect.

(d) Diazonium salts of aromatic amines are more stable than that of aliphatic amines

(a)  Aniline is a strong lewis base and the catalyst used (AlCl₃) is a strong lewis acid.

(b) maximum number of hydrogen bonds are present in primary amines so it has more boiling points.

(c) because the lone pair on the nitrogen atom is in conjugation with the carbonyl group in acetylated aniline.

(d) Due to resonance-induced positive charge dispersion over the benzene ring, aromatic diazonium salts are more stable than aliphatic diazonium salts.
