Question

Assertion (A) : Alkene A $(M{e}_{2}C=CM{e}_2)$ is more stable than alkene $(E{t}_{2}C=CE{t}_2)$.
Reason (R) : Baker-Nathan effect.

• A. If both (A) and (R) are true and (R) is the correct explanation of (A).
• B. If both (A) and (R) are true and (R) is not the correct explanation of (A).
• C. If (A) is true but (R) if false
• D. If (A) is false but (R) if true

Answer 1

The correct option is A If both (A) and (R) are true and (R) is the correct explanation of (A).


Double bond having more $\alpha -H$ is more stable due to hyperconjugation.
Hyperconjugation is also known as Baker-Nathan effect.
