Mesomeric effect in acids.

    Why there is no mesomeric interaction between [itex]\pi[/itex]-electrons of aromatic ring and [itex]\pi[/itex]-electrons of carbonyl group in benzoic acids?

    I would think it was because the postive charge was bourne fully by the dissociated proton rather than the carbonyl carbon attached to the aromatic ring.

    There are no valid resonance structures satisfying the octet rule.
