Hydrocarbons are compounds made from carbon and hydrogen atoms joined by covalent bonds. Alkanes are saturated-they have only single bonds.Alkenes have a double bond-they are unsaturated. Alkenes react with brown bromine water and decolourise it, but alkanes do not.Alkenes can act as monomers.ydrocarbons are compounds made from carbon and hydrogen atoms joined by covalent bonds.

Chemical Properties and Reactions of Alkanes. Alkanes generally show low reactivity, because their C-C bonds are stable and cannot be easily broken. As they are inert against ionic or other polar substances they are also called paraffins (Latin para + affinis = lacking affinity).he halogenation reactions of alkanes are quite different, depending on the involved halogen. While flourine reacts explosively with alkanes and can hardly be controlled, chlorine and bromine react satisfactorily (bromine much slower than chlorine), and iodine is unreactive.
