Question

Among acetic acid, phenol and n-hexanol, which
of the following compounds well react with
NaHCO₃ solution to give sodium salt and carbon dioxide ?
(a) Acetic acid
(b) n-Hexanol
(c) Acetic acid and phenol
(d) Phenol

Answer 1

(a) Acetic acid

Explanation:

Phenol is not acidic enough to react with sodium bicarbonate or sodium carbonate.

n-hexanol is neutral in nature.

Acetic acid neutralizes sodium bicarbonate to give sodium acetate with the liberation of carbon dioxide gas.

CH3COOH + NaHCO3 ---> CH3COONa + CO2 + H2O

Option A is the correct answer.
