Verified Answer
Select the correct statement:a) is more basic thanb) is more basic...
Benzoic acid is a stronger acid than phenol because the benzoate ion is stabilised by two equivalent resonance structures in which the negative charge is present at the more electronegative oxygen atom.
The conjugate base of phenol, a phenoxide ion, has non-equivalent resonance structures in which the negative charge is at the less electronegative carbon atom. Thus, the benzoate ion is more stable than phenoxide ion. Hence, benzoic acid is a stronger acid than phenol.

In option A lone pairs of aniline are involved in resonance hence it is less basic
in option B N in pyridine is sp2 therefore it is more electronegative than Nitrogen in piperidine
in option C lone pairs of oxygen in carboxylate ion is resonance between 2 electronegative oxygen while in phenoxide ion the lone pairs are resonance between one oxygen atom and benzene ring hence it is difficult to donate electrons by the carboxylate ion
hence carboxylate ion is less basic than phenoxide ion.
option C is correct
in option B N in pyridine is sp2 therefore it is more electronegative than Nitrogen in piperidine
in option C lone pairs of oxygen in carboxylate ion is resonance between 2 electronegative oxygen while in phenoxide ion the lone pairs are resonance between one oxygen atom and benzene ring hence it is difficult to donate electrons by the carboxylate ion

Conjugate acid of ph-O(-) is phenol and conjugate acid of ph -COO(-) is benzoic acid...and benzoic acid is more acidic than phenol ...so ph-O(-) is more basic than ph-COO (-)
