MCQ

Hydrogen bonding does not play a central role in the following phenomena

A
Ice floats in water
B
Higher lewis basicity of primary amines than tertiary amines in aqueous solutions
✓
Formic acid is more acidic than acetic acid
D
Dimerisation of acetic acid in benzene

✓

Answer

Correct option: C.

Formic acid is more acidic than acetic acid

(C) Formic acid is more acidic because it has lesser number of alkyl groups attached and hence, lesser the $+ I$ effect of alkyl groups.
