THE HYDROGENATION OF ALKENES. This page looks at the reaction of the carbon-carbon double bond in alkenes with hydrogen in the presence of a metal catalyst. This is called hydrogenation. It includes the manufacture of margarine from animal or vegetable fats and oils. Hydrogenation in the lab. The hydrogenation of ethene.
Alkenes have less hydrogen atoms than alkanes. C 2 H 4 CH 2 =CH 2 C 3 H 6 CH 2 =CH-CH 3 Alkynes: an unsaturated hydrocarbon that contains one or more carbon-carbon triple bonds. The molecular formula of this group is C n H 2n-2 (n is the number of carbon atoms).r.
