Question

Draw the product of the following reaction.  

**Hydrogenation of Alkynes Using Lindlar's Catalyst** In this diagram, we have the chemical reaction showing the hydrogenation of an alkyne. On the left side, there is a linear structure representing an alkyne, which contains a carbon-carbon triple bond. An arrow points to the right, indicating the direction of the chemical reaction. Above the arrow, it is labeled "H₂, Lindlar's cat." This signifies that the reaction involves hydrogen gas (H₂) in the presence of Lindlar's catalyst. Lindlar's catalyst is often used to selectively hydrogenate alkynes to cis-alkenes, preventing further reduction to alkanes. This reaction is key for the preparation of alkenes with a specific geometry in organic synthesis.
