Careful measurements reveal that para-methoxybenzoic acid is less acidic than benzoic acid, while meta-methoxybenzoic acid is more acidic than benzoic acid. Explain these observations. The methoxy group is electron donating via resonance, but electron withdrawing via induction. The resonance effect is weaker, but only occurs when the methoxy group is in an ortho or para positon.
