Vedclass · Answer

(C) $NaHCO_3$ is a mild base and only compounds more acidic than carbonic acid $(H_2CO_3)$ can react with it to evolve $CO_2$ gas.Carboxylic acids are significantly more acidic than phenols and amines.Compound $(III)$ is benzoic acid and compound $(IV)$ is $p$-nitrobenzoic acid.Both $(III)$ and $(IV)$ are carboxylic acids and are strong enough to react with $NaHCO_3$.Compound $(I)$ is an amine-substituted phenol and compound $(II)$ is phenol; both are less acidic than $H_2CO_3$ and do not react with $NaHCO_3$.Therefore,only $(III)$ and $(IV)$ react with $NaHCO_3$.

Which of the following set of compounds react with $NaHCO_3$?
