`[A] underset("Catalyst")overset(H_2//"Lindler's")larr CH_3 - C -= C-CH_3 underset(liq. NH_3)overset(Na " in ")to [B] , ` [A] and [B] respectively are

A

cis, trans -2-butene

B

both trans-2-butene

C

trans, cis-2-butene

D

both cis-2-butene

Text Solution

Verified by Experts

The correct Answer is:
A
Reduction of 2-butyne with H, in presence of Lindlar.s catalyst `(pd-BaSO_4)` gives cis-2-butene while with Na/liq.`NH_3` (Brich reduction) gives trans -2-butene
