Question

In 2-butene, which one of the following statements is true
A. `C_(1)-C_(2)` bond is a `sp^(2) - sp^(3) sigma`-bond
B. `C_(2)-C_(3)` bond is a `sp^(3) - sp^(2) sigma`-bond
C. `C_(1) -C_(2)` bond is a `sp^(3) - sp^(2) sigma` - bond
D. `C_(1) - C_(2)` bond is a `sp^(2) - sp^(2) sigma`- bond

Answer 1

Correct Answer - C
`underset("(2-butene)")(underset(sp^(3))(overset(1)(C)H_(3))-underset(sp^(2))(overset(2)(C)H)=underset(sp^(2))(overset(3)H)-underset(sp^(3))(overset(4)(C)H_(3)))`
`{:(C_(1)-C_(2) rArr sp^(3)-sp^(2),,sigma-"bond"),(C_(2)-C_(3) rArr sp^(2)-sp^(2),,sigma-"bond"):}`
