Question

Which of the following is correct for stability of phenoxide ion?

• A. Resonating structure of benzenering
• B. Localization of $\pi$-electrons in phenoxideion
• C. Delocalization of $\pi$-electrons in phenoxide ion.
• D. All of the above

Answer 1

Answer: (C)

Delocalization of $\pi$-electrons in phenoxide ion.

It is due to delocalisation of negative charge. In phenoxide ion oxygen has high electron density as it is highly electronegative in nature and it is stabilised by resonance. So the phenoxide ion is very stable.
