Assertion (A): Carboxylic acids are more acidic than Phenols Reason (R): Resonance structures of carboxylate ion are equivalent, while resonance structures of phenoxide ion are not equivalent
  1. Both and (R) are correct and (R) is the correct explanation of $(\mathrm{A})$
  2. Both and (R) are correct But (R) is not the correct explanation of $(\mathrm{A})$
  3. is correct but (R) is incorrect
  4. is incorrect but (R) is correct

Solution

Carboxylic acid is stronger because its resonating structures more stable than the phenol. Carboxylic acid:
Negative charge on more electronegative oxygen atom so both resonating structure are equal.
Negative charge is on carbon which leads to less stability of phenoxide than carboxylate ion
