For distinguishing phenol and acetic acid we required to react (treat) them with
Options
(a) Na₂CO₃
(b) NaOH
(c) HCl
(d) NaHCO₃
Correct Answer:
NaHCO₃
Explanation:
Acetic acid on treatment with NaHCO₃ evolves CO₂, however no such reaction occurs with phenol. CH₃COOH + NaHCO₃ → CH₃COONa + CO₂↑ + H₂O.
