The least stable carbanion is _____?

کم سے کم مستحکم کاربنین _____ ہے؟

(CH₃)₃C⁻

CH₃⁻

(CH₃)₂C⁻

None of these

The tertiary carbanion (CH₃)₃C⁻ is the least stable because the negative charge is not effectively stabilized by resonance or inductive effects.

Tertiary carbanions are highly unstable compared to secondary and primary carbanions.
