Hydrogenation involves adding hydrogen \((\text{H}_{2})\) to an alkene. During hydrogenation the double bond is broken (as with hydrohalogenation and halogenation) and more hydrogen atoms are added to the molecule. A specific example is shown in Figure 4.82. Figure 4.81: The hydrogenation of ethene to ethane. Reaction conditions: Absorption of light by the W(CO)5(cis-2-pentene) does take place and can lead directly to a species which catalytically interconverts the pentenes by photodissociation of CO, equation (15).

One or more of the hydrogen atoms on a benzene ring can be replaced by other atoms. When two hydrogen atoms are replaced, the product name is based on the relative position of the replacement atoms (or atom groups).
