A compound dissolves in aqueous NaOH but does not release CO₂ with NaHCO₃. Which compound fits this behaviour?
Correct answer B. Phenol
Explanation
Phenol is acidic enough to react with NaOH to form sodium phenoxide, but it is a weaker acid than carbonic acid, so it cannot release CO₂ from NaHCO₃. Carboxylic acids do both and ethanol does neither.
