Question

Is triple bond carbanion more stable than double bond carbanion?

Answer 1

Answer:triple bond carbanion

Explanation:

Stability also depends on hybridisation of the negative charge bearing atom- greater the s character, more is the stability of carbanion.

Here, in triple bond carbanion, carbon bearing negative charge is sp hybridised, it means it has 1/2 s character while In case of double bond carbanion, carbon bearing negative charge is sp2 hybridised ,and thus it has 1/3 s character..
