"Unsaturated" refers to the fact that each of the carbons bonds aren't with 4 separate molecules, but can, instead have double or triple bonds.A hydrocarbon in which valencies of carbon are not satisfied by single covalent bonds are unsaturated hydrocarbons. There are three types of unsaturated hydrocarbons: *[[alkenes]] *[[alkynes]] *[[dienes]] (plus ''polyenes'' and ''poly-ynes'') The physical properties of unsaturated hydrocarbons are very similar to those of the corresponding saturated compounds. They are slightly soluble in water. Except for [[aromatic]] compounds, unsaturated hydrocarbons are highly reactive and undergo [[addition reaction]]s to their multiple bonds. Typical reagents added are [[hydrogen]] [[halide]]s, [[water]], [[sulfuric acid]], elemental [[halogen]]s and [[alcohol]]s. ==Testing== To test whether the [[hydrocarbon]] is unsaturated you should add bromine water. If the [[bromine water]] becomes decolourised (Goes clear)then it is unsaturated ==See also== *[[saturated hydrocarbon]] [[Category:Organic chemistry]] [[ar:هيدروكربون غير مشبع]] [[es:Hidrocarburo insaturado]] [[ja:不飽和炭化水素]] [[lv:Nepiesātinātie ogļūdeņraži]] [[pt:Hidrocarboneto alifático]] [[zh:不饱和烃]]
