WebSubstituents, particularly those located ortho or para to the -OH group, can dramatically influence the acidity of the phenol due to resonance and / or inductive effects. Electron withdrawing groups enhance the acidity, electron donating substituents decrease the acidity. The resonance stabilisation of o-nitrophenol is shown below: go threadxWebThe phenolate ion can also be stabilised by resonance but the charge ends up on C atoms. In contrast, the alkoxide ion has no resonance stabilisation since there is no π system. (b) All these structures are p -substituted phenols, so the substituent must be the controlling factor. The effect the substituent exerts on the benzene ring will ... childcare floor plan drawing
