Q. Which of the following compound would not evolve $CO_2$ when treated with $NaHCO_3$ solution ?
KCET
KCET 2006
Aldehydes Ketones and Carboxylic Acids
A
salicylic acid
20%
B
phenol
46%
C
benzoic acid
18%
D
4-nitro benzoic acid

Solution:
Phenol does not decompose sodium carbonate or sodium bicarbonate i.e., $CO _{2}$ is not evolved, because phenol is a weaker acid than carbonic acid.
