Compounds of carbon and hydrogen that contain one double bond between carbon atoms (carbon=carbon) or a triple bond between carbon atoms (carbon≡carbon) are called unsaturated hydrocarbons. In these molecules, since all the bonds of carbon are not fully utilized by hydrogen atoms, more of these can be attached to them. Thus, they undergo addition reactions (add on hydrogen) as they have two or more hydrogen atoms less than the saturated hydrocarbons (alkanes).

Saturated hydrocarbons have only singal bonds, which are very stable and hard to break. Unsaturated hydrocarbons have [usually one - and often two or three-] pi [Carbon=Carbon double] bonds, and they are weaker. They deform the orbitals slightly and are more strained. Therefore, they are easier to break and will react faster
