Question

Consider the following alkenes :
1. `H_(2)C=C(CH_(2)CH_(3))CH(CH_(3))_(2)`
2. `(CH_(3))_(2)C=C(CH_(3))CH_(2)CH_(3)`
3. `CH_(3)CH=C(CH_(3))CH(CH_(3))_(2)`
The correct sequence of increasing order of stability of these alkenes is :
A. 1,2,3
B. 3,2,1
C. 2,1,3
D. 1,3,2.

Answer 1

Correct Answer - D

Correct order of stability on the basis of hyperconjugation is `1lt3lt2 `
