A

A) `(CH_3)_2CH-CN`

B

B) `CH_2=CH-CH_2CN`

C

C) `Br - CH=CH-CN`

D

D) `CH_2=CH- underset(Br)underset(|)CHCN`

Text Solution

Verified by Experts

The correct Answer is:
B
`C_3H_7I overset("Alcoholic")underset(KOH) rarr CH_2 = CH-CH_3 overset(NBS)underset(Delta) rarr CH_2=CH-overset(Br)overset(|)CH_2 overset(NaCN)overset("Alcoholic")rarr CH_2 = CH-CH_2-CN`
