Consider the following sequence of reactions:
`H_(2)C=CH-CH=CH_(2)overset(Br_(2)("1Mole"))underset("CCl"_(4))toA overset("1.KCN(excess)")underset(2.H_(2),Ni)toB`. The end product (B) is :

A

`H_(2)N-(CH_(2))_(2)-CH=CH-(CH_(2))_(2)-NH_(2)`

B

`H_(2)N-(CH_(2))_(6)-NH_(2)`

C

`NC-CH_(2)-CH=CH-CH_(2)-CN`

D

`H_(2)C=CH-underset(NH_(2))underset(|)CH-(CH_(2))_(2)-NH_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`H_(2)C=CH-CH=CH_(2)overset(Br_(2)(1" mole"))underset("CCl"^(4))toH_(2)underset(Br)underset(|)C=CH=CH-underset(Br)underset(|)CH_(2)overset(KCN,H_(2),Ni)tounderset(" NH"_(2)-NH_(2))underset(|)(" H"_(2)C-CH_(2))-underset(" CH"_(2)NH_(2))underset(" "|)(CH_(2)-CH_(2))`
