`Aoverset(H_(2)//"Lindlar's catalyst")larrCH_3C-=C CH_(3)overset(Na//Liq" "NH_(3))toB` A and B, respectively, are

A

A is cis while B is trans-2-butene

B

A is trans while B is cis-2-butene

C

A and B both are trans-2-butene

D

A and B both are cis-2-butene

Text Solution

Verified by Experts

The correct Answer is:
A
`Ni_(2)B(P-2 "catalyst")` gives cis alkune while Na in liquid `NH_(3)` (Birch reduciton) gives trans alkene.
