Question

Which of following is true with respect to resonance stabilization in phenolate ion $C_6{H}_5{O}^{-}$ and phenol $C_6{H}_{5}OH$?

• A. $C_6{H}_5{O}^{-}$ > $C_6{H}_{5}OH$
• B. $C_6{H}_5{O}^{-}$ < $C_6{H}_{5}OH$
• C. $C_6{H}_5{O}^{-}$ = $C_6{H}_{5}OH$
• D. None of the above

Answer 1

The correct option is A $C_6{H}_5{O}^{-}$ > $C_6{H}_{5}OH$

With respect to stabilization $C_6{H}_5^{-}>C_6{H}_{5}OH$ is more stable because $+$ and $-$ charges are present in $C_6{H}_{5}OH$ due to this stabilization energy decreases.
