`Ph-CH_(2)-CH_(2)-C-=C-CH_(3)overset(Na//NH_(3))to overset(Cl_(2)//hv)to`

A

B

C

`Ph -CH_(2)-CH(Cl)-CH=CH-CH_(3)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
`Ph-CH_(2)-CH_(2)-C-=C-CH_(3)overset(Na//NH_(3))to`

`Na//NH_(3)(l)` this is Birch reduction reduce only alkyne into trans alkene and `Cl_(2)//hv` is free readical substitution reaction
