Question

In which of the following species hyperconjugation is possible?

• A. $CH_{3} - \overset{-}{C}H_{2}$
• B. $C_{6}H_{5} - CH_{3}$
• C. $CH_{2} = CH_{2}$
• D.

Answer 1

Answer: (B)

$C_{6}H_{5} - CH_{3}$

Answer 2

: Hyperconjugation is orbital interactions between $\pi -$ systems and the adjacent $\sigma$ bond of substituent groups for hyperconjugation $\alpha$ - carbon with respect to $sp^{2}$ hybrid carbon should have at least one hydrogen.
