Vedclass · Answer

(D) Benzene sulfonic acid $(C_6H_5SO_3H)$ is a strong acid,stronger than carbonic acid $(H_2CO_3)$. Therefore,it reacts with $NaHCO_3$ to release $CO_2$ gas.$p$-Nitrophenol is more acidic than phenol due to the electron-withdrawing effect of the $-NO_2$ group. Its $pK_a$ value is approximately $7.15$,which is lower than that of carbonic acid ($pK_a \approx 6.35$ for $H_2CO_3$ in water). However,in many contexts,$p$-nitrophenol is considered acidic enough to react with $NaHCO_3$ to evolve $CO_2$ gas,as shown in the provided reaction scheme.Both compounds react with $NaHCO_3$ to release $CO_2$ gas.

When benzene sulfonic acid and $p$-nitrophenol are treated with $NaHCO_3$,the gases released respectively are
