Question

Both compounds X and Y are only sparingly soluble in water. Both X and Y react with sodium metal with liberation of $\mathrm{H_2}$ and are soluble in 5% aqueous NaOH. Compound X liberates $\mathrm{CO_2}$ from sodium bicarbonate while compound Y is unreactive towards sodium bicarbonate. X and Y are __________ and __________ respectively.

Accepted Answer

D - aromatic carboxylic acid and phenol. Both are acidic (react with Na, dissolve in NaOH). Only a carboxylic acid ($\mathrm{p}K_\mathrm{a}$ about 4-5) is acidic enough to liberate $\mathrm{CO_2}$ from $\mathrm{NaHCO_3}$; a phenol ($\mathrm{p}K_\mathrm{a}$ about 10) is not. Being sparingly…
