Vedclass · Answer

(A) The reaction of $2$-butyne $(CH_3-C \equiv C-CH_3)$ with $Pd-BaSO_4$ in the presence of $H_2$ is known as the Lindlar's catalyst reduction.This reaction involves the syn-addition of hydrogen to the triple bond.As a result,the alkyne is reduced to a $cis$-alkene.Therefore,$2$-butyne yields $cis-2$-butene.

When $2$-butyne is treated with $Pd-BaSO_4$ (Lindlar's catalyst),the product formed will be:
