How convert 2 butyne into Cis and trans 2 butene

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.
