Question

Acetamide behaves as a weak base in aqueous solution but shows acidic properties in liquid ammonia.

Answer 1

because acetamide is amphoteric in nature which act as both acid and base.

Answer 2

Hey dear,
Molecular formula of acetamide is CH3-CO-NH2.

● Acetamide in aqueous solution -
Acetamide dissolves in water to form hydroxyl (OH-) ions. Hence, it acts as weak base in aqueous solution.


● Acetamide in liquid ammonia -
Acetamide dissolves in liquid NH3 to form ammonium(NH4+) ions. Hence, it acts as weak acid in liquid ammonia.
