STANDARD Chemistry Stability of Alkenes MCQ Question
Type: MCQ-conceptual-Medium
Decreasing order of stability of following alkenes is (i) CH₃−CH=CH₂ (ii) CH₃−CH=CH−CH₃ (iii) CH₃−C=CH−CH₃ (iv) CH₃−C≡C−CH₃
A
(i) > (ii) > (iii) > (iv)
B
(iv) > (iii) > (ii) > (i)
C
(iii) > (ii) > (i) > (iv)
D
(ii) > (iii) > (iv) > (i)
Correct Answer
Option B
Detailed Explanation
Higher the number of α-H, more the hyper-conjugating structures, more the stability of the compound. Alkyne (iv) is most stable due to sp hybridization, followed by (iii), (ii), and (i).
