Question

Which of the following is the most stable alkene?

(a) CH₂ = CHR

(b) RCH = CHR

(c) R₂C = CR₂

(d) CH₂ = CH₂

Answer 1

Correct option (d) CH₂ = CH₂

Explanation:

Alkenes are reactive due to the presence of double bond. The n electrons arc loosely held and are there[ore. easily polarisable. So more the number of electron releasing alkyl group on the double bond, lesser is the stability.
