Chemical reaction in which the atoms of an element or compound react with a double bond or triple bond in an organic compound by opening up one of the bonds and becoming attached to it, for example:
CH2CH2 + HCl ® CH3CH2Cl
Another example is the addition of hydrogen atoms to unsaturated compounds
in vegetable oils to produce margarine. Addition reactions are used to make polymers from alkenes
