1.	Assertion: The `pK_(a)` of acetic acid is lower than that of phenol. Reason : Phenoxide ion is more resonance sabilised.A. If both assertion and reason are true and the reason is the correct explanantion of the assertion.B. If both assertion and reason are true but reason is not the correct explanantion of the asseriton.C. If assertion is true but reason is false.D. If assertion if false but reason is ture.
Answer» Correct Answer - C Lower the value of `pKa`, more acidic will be the compound. Acetic acid is more acidic than phenol. This indicates that carboxylate ion should be more stable than the phenoxide ion and it is clear that carboxylate ion has more equivalent resonating structures than the phenoxide ion.
