Vedclass · Answer

(B) The reaction of an alkyne with $H_2$ in the presence of $Pd/CaCO_3$ (Lindlar's catalyst) is a controlled hydrogenation reaction. This catalyst partially reduces the alkyne to an alkene. Specifically,this reaction follows syn-addition,which results in the formation of the cis-isomer. Therefore,$4$-octyne reacts with $H_2$ over $Pd/CaCO_3$ to yield cis-$4$-octene.

What is the product formed when $4$-octyne reacts with $H_2$ in the presence of $Pd/CaCO_3$?
