Which is the correct increasing order of the stability of isomers of pentene ?
(1) CH3–CH2–CH2–CH=CH2 (2)
(3) 
(4) 
A
1 < 2 < 3 < 4
B
1 < 3 < 2 < 4
C
4 > 3 > 2 > 1
D
4 < 2 < 3 < 1
Answer
1 < 2 < 3 < 4
Explanation
Solution
Stability depends on hyperconjugation which further depends on total number of aH.
