Although phenoxide ion has more number of resonating structures than carboxylate ion, carboxylic acid is a stronger acid than phenol because -

1) carboxylate ion has more lattice energy than phenoxide ion

2) phenoxide ion has more lattice energy than carboxylate ion

3) carboxylate ion is more resonance-stabilized than phenoxide ion

4) phenoxide ion is more resonance-stabilized than carboxylate ion
