Reactions of Alkenes and Alkynes - How can an Alkene be Reduced to an Alkane?
3 important questions on Reactions of Alkenes and Alkynes - How can an Alkene be Reduced to an Alkane?
How can an alkene be reduced to alkane?
By catalytic reduction also named catalytic hydrogenation.
Is catalytic reduction stereoselective?
Yes, the most common pattern is syn addition.
Describe the mechanism of syn addition.
The metal catalyst adsorb hydrogen onto their surface, by formation of a metal-hydrogen sigma bond. This happens also to the alkenes, breaking the pi bond and forming a sigma bond with the metal.
