Question

Which of the following orders is correct for the stability of these carbanions?

• A. I $>$ II $>$ III
• B. III $>$ II $>$ I
• C. II $>$ III $>$ I
• D. II $>$ I $>$ III

Answer 1

The correct option is A I $>$ II $>$ III

The Carbanion is more stable when, the there is a group near to it which attracts electrons towards it or a group which shows -I effect. Therefore the carbanion formed at the ortho position is more stable than meta which is stable than at para.

hence A) is correct option
