JEE Main Chemistry question

Which of the following compounds yields the most stable carbanion after rupture of the C1–C2 bond shown?

(A)CH₃–CO–CHI₂ (bond to CHI₂)
(B)CH₃CH₂–CO–CCl₃ (bond to CCl₃)Correct
(C)CH₃–CO–CH₂I (bond to CH₂I)
(D)None of these

Answer: (B)

Solution

The resulting carbanion is stabilized both by resonance with the adjacent carbonyl and by the inductive (−I) withdrawal of the halogens on that carbon.
