Which of the following compound would not evolve CO_2 when treated with NaHCO_3 solution?

Correct answer: (B) Phenol. Phenol does not decompose sodium bicarbonate (NaHCO_3 ) as it is a weaker acid than carbonic acid. ∴ CO_2 gas is not evolved by phenol.

Which of the following compound would not evolve $\mathrm{CO}_{2}$ when treated with $\mathrm{NaHCO}_{3}$ solution?

A
Salicylic acid
Correct answer
B
Phenol
C
Benzoic acid
D
4-nitro benzoic acid

Solution

Phenol does not decompose sodium bicarbonate $\left(\mathrm{NaHCO}_{3}\right)$ as it is a weaker acid than carbonic acid. $\therefore \mathrm{CO}_{2}$ gas is not evolved by phenol.

Hence, the correct answer is option: 'B'.
