Question

Which of the following is the most stable alkene? (A) RCH 2= CH 2 R (B) RCH = CHR (C) R 2 C = CR 2 (D) CH 2= CH 2

Alkenes are reactive due to the presence of double bond. The π -electrons are loosely held and are therefore, earily polaisable. So more the number of e -1 releasing alkyl group on the double bond, lesser is the stability.

Q. Which of the following is the most stable alkene?

$RC H_{2} = C H_{2} R$

$RC H = C H R$

$R_{2} C = C R_{2}$

$C H_{2} = C H_{2}$

Alkenes are reactive due to the presence of double bond. The $π$ -electrons are loosely held and are therefore, earily polaisable. So more the number of $e^{- 1}$ releasing alkyl group on the double bond, lesser is the stability.

RCH2​=CH2​R

RCH=CHR

R2​C=CR2​

CH2​=CH2​
