(A) Lindlar's catalyst is a poisoned palladium catalyst ($Pd/CaCO_3$ or $Pd/BaSO_4$ poisoned with quinoline or sulfur).It performs the partial hydrogenation of alkynes to alkenes.The reaction is stereospecific and yields the $cis-$alkene.The reaction is:$CH_3-C \equiv C-CH_3 + H_2 \xrightarrow{Pd/CaCO_3} cis-CH_3-CH=CH-CH_3$Thus,the hydrogenation of $2-$Butyne with Lindlar's catalyst produces $cis-2-$Butene.

Hydrogenation of $2-$Butyne in the presence of Lindlar's catalyst gives
