Introduction

An addition reaction is one in which two parts of a molecule are added to an unsaturated molecule, increasing the saturation of a molecule. Addition reactions are limited to chemical compounds that have multiple bonds, such as molecules with carbon-carbon double bonds, or with triple bonds. Molecules that have carbonyl groups, or imine groups, can undergo addition because they have double bond characters. Addition reactions are opposites of elimination reaction. A common type of addition reaction is hydrogenation. In hydrogenation, hydrogen atoms are added to an unsaturated molecule.
