Question

Chemistry Question on Hydrocarbons

HC == C−^{-} is more stable than HC == CH−^{-}. HC == C−^{-} has more s-character than HC == CH−^{-}.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

If assertion is true but reason is false

D

If both assertion and reason are false

Answer

If both assertion and reason are true and reason is the correct explanation of assertion

Explanation

Solution

HC == C−^{-} has 50% s-character and HC == CH−^{-} has 33% s-character. Stability of carbanions increases with an increase in the s-character at the carbanion. So HC == C−^{-} is more stable than HC == CH−^{-}.
