Question

Transcribed Image Text:What will happen if the shown hydrogenation reaction is done using Lindlar's catalyst?
**Diagram:**
- A chemical structure is depicted with an alkyne group (a carbon-carbon triple bond) connected to a cyclic compound with two fluorine atoms attached.
**Reaction:**
- Hydrogen (\(H_2\)) is indicated as a reactant in the presence of Lindlar's catalyst.
**Options:**
1. It will cause an oxidation of the shown alkyne.
2. It will result in a *syn* addition of hydrogens, forming an \(E\)-alkene.
3. It will result in an *anti* addition of hydrogens, forming an \(E\)-alkene.
4. It will result in an *anti* addition of hydrogens, forming a \(Z\)-alkene.
5. It will result in a *syn* addition of hydrogens, forming a \(Z\)-alkene.
**Explanation:**
Lindlar's catalyst typically results in a syn addition of hydrogens to an alkyne, creating a cis (Z) alkene.
