A

`CH_3 -CH=CH_2`

B

`CH_3 -CH=CH-CH_3`

C

`CH_3-underset(CH_3)underset(|)C=underset(CH_3)underset(|)C-CH_3`

D

`CH_2=CH_2`

Text Solution

Verified by Experts

The correct Answer is:
C
has highest C - C bond length (B.L.) , Because it has maximum hyperconjugation.
More single bond character by hyperconjugatio.
