Question

Which of the two structures $\left(A\right)$ and $\left(B\right)$ given below is more stabilized by resonance? Explain.

$C{H}_{3}COOH$ and $C{H}_{3}CO{O}^{-}$
$\left(A\right)$ $\left(B\right)$

Answer 1

A canonical structure without having any charge separation is more stable than a canonical structure having charge separation.

Hence, structure ${}^{\prime }{B}^{\prime }$ is more stabilized, as it does not involve charge separation during resonance.
