Question

The hydrogenation reaction of an alkyne using the Lindlar catalyst always gives a cis-alkene. Explain why.

Chemical reaction showing alkyne hydrogenation to cis-alkene using Lindlar catalyst.

Accepted Answer

Because both hydrogens are added to the same face of the alkyne in a concerted manner.

Answer

Because the hydrogens are added to different faces of the alkyne.

Answer

Because of the higher stability of the cis alkene.

Answer

None of these.

The hydrogenation reaction of an alkyne using the Lindlar catalyst always gives acis-alkene. Explain why.
