Question

How convert 2 butyne into Cis and trans 2 butene

Answer 1

Answer:

When 2-butyne is reduced selectively to cis-2-butene, a carbon-carbon triple bond is reduced to cis carbon-carbon double bond. Usually, complete reduction of alkynes gives alkanes. In these reduction reactions, the carbon-carbon triple bond is reduced to the carbon-carbon single bond.
