Question

mechanism of hydrogenetion​

Answer 1

.THE MECHANISM OF HYDROGENATION

This reaction is an example of a heterogeneous catalysis process.

The reaction takes place on the surface of the metal.

STEP 1:

Hydrogen molecules react with the metal atoms at the catalyst surface.

The relatively strong H-H sigma bond is broken and replaced with two weak metal-H bonds.

STEP 2:

The pi bond of the alkene interacts with the metal catalyst weakening the bond.

A hydrogen atom is transferred from the catalyst surface to one of the carbons of the double bond.

STEP 3:

The pi bond of the alkene interacts with the metal catalyst weakening the bond.

A second hydrogen atom is transferred from the catalyst surface forming the alkane.

Answer 2

hydrogenation:

 – meaning, to treat with hydrogen – is a chemical reaction between molecular hydrogen (H2) and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum. The process is commonly employed to reduce or saturate organic compounds.
