$2,4,6-$Trinitrophenol

Vedclass · Answer

(A) Compounds that are stronger acids than carbonic acid $(H_2CO_3)$ react with sodium bicarbonate $(NaHCO_3)$ to release carbon dioxide $(CO_2)$ gas, which causes effervescence.$2,4,6-$Trinitrophenol (also known as picric acid) is a strong acid due to the electron-withdrawing effect of three nitro $(-NO_2)$ groups, which stabilize the phenoxide ion.Since the $pK_a$ of picric acid is lower than the $pK_a$ of $H_2CO_3$, it reacts with $NaHCO_3$ to produce effervescence.Other options like acetone, ethanol, and diethyl ether are not acidic enough to react with $NaHCO_3$.

Which of the following compounds will produce effervescence when mixed with an aqueous sodium bicarbonate $(NaHCO_3)$ solution?
