JEE Main Chemistry question

Which one of the following carbanions is the least stable?

(A)CH₃CH₂⁻
(B)HC≡C⁻
(C)(C₆H₅)₃C⁻
(D)(CH₃)₃C⁻Correct

Answer: (D)

Solution

Unlike carbocations, carbanions are destabilized by electron-donating alkyl groups (which push additional electron density onto an already negative carbon). (CH₃)₃C⁻ bears three electron-donating methyls and is therefore the most
