The major product of the following reaction is :
`CH_(3)underset(overset(|)(Br))(C)HCH_(2)underset(overset(|)(Br))(C)HCH_(2)CH_(3) underset("heat")overset(KOH, CH_(3)OH)(to)`

A

`CH_(2)=CHCH_(2)CH =CHCH_(3)`

B

`CH_(2)=CHCH=CHCH_(2)CH_(3)`

C

`CH_(3)CH=C=CHCH_(2)CH_(3)`

D

`CH_(3)CH=CH-CH=CHCH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
It is dehydrobromination and major product is formed according to saytzeff’s rule. Conjugated and more substituted diene is more stable.
`CH_(3)-underset(Br)underset(|)(CH) -CH_(2) -underset(Br) underset(|)(CH)-CH_(2)-CH_(3)underset("Heat")overset(KOH,CH_(3)OH)toCH_(3)-CH=CH-CH=CH-CH_(3)`
