Question

In which of the following species hyperconjugation in possible?
A. `CH_(3)-overset(-)(C)H_(2)`
B. `C_(6)H_(5)-CH_(3)`
C. `CH_(2)=CH_(2)`
D. `CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-CH=CH_(2)`

Answer 1

Correct Answer - B
For hyperconjugation `alpha`-carbon with respect to `sp^(2)` hybridised carbon should have at least one hydrogen.
