But-2-`"ene" underset(C Cl_(4))overset(N-"Bromosuccinimide")rarr`
The product formed in the reaction is

A

`CH_(3)CH=C(Br)CH_(3)`

B

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

C

`CH_(3)CH(Br)CH(Br)CH_(3)`

D

`CH_(3)C(Br)=C(Br)CH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
NBS `(N-"bromosuccinimide")` in `C Cl_(4)` in the presence of peroxides or light causes allylic bromination.
`CH_(3)-CH=CH-CH_(2)-underset("Allylic H atom")underset(uarr)Hoverset(NBS)rarrCH_(3)CH=underset(Br)underset(|)underset(CH_(2))underset(|)CH`
