Pyridine is less basic than triethylamine because

• pyridine has aromatic character

• nitrogen in pyridine is sp² hybridised

• pyridine is a cyclic system

• in pyridine, lone pair of nitrogen is delocalised

Assertion: Anilinium chloride is more acidic than ammonium chloride.

Reason : Anilinium ion is resonance-stabilised.

307.

Melting points are normally the highest for

• tertiary amides

• secondary amides

• primary amides

• amines.

Assertion: Boiling and melting points of amides are higher than corresponding acids.
Reason: It is due to strong intermolecular hydrogen bonding in their molecules.

The basicity of aniline is weaker in comparison to that of methylamine due to:

• hyper conjugative effect of Me-group in MeNH₂

• resonance effect of the phenyl group in aniline

• the lower molecular weight of methylamine as compared to that of aniline

• resonance effect of -NH₂ group in MeNH₂
