A

CH_3 CH= CHCH_3` predominates

B

`CH_2 = CHCH_2 CH_3` predominates

C

Text Solution

Verified by Experts

The correct Answer is:
A
`CH_(3)-CH_(2)-CH_(2)-CH_(3) overset(H_2SO_4)underset(475 K) rarr underset("More symmetrical (major product)")(CH_3-CH=CH-CH_3)`
`CH_(3)-CH_(2)-CH_(2)-CH_(3) overset(H_2SO_4)underset(475K)rarr underset("(minor product)")underset("unsymmetrical")underset("Less symmetrical or ")(CH_(2)=CH-CH_(2)-CH_(3))`
It is based on Saytzeff’s rule. According to this more symmetrical or more alkylated alkene predominates.
