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. Alkanes are saturated-they have only single bonds.
â¢ In saturated hydrocarbons, all the bonds are single bonds. In unsaturated hydrocarbons, double bonds and triple bonds are also present. â¢ Saturated hydrocarbons have the highest number of hydrogen atoms, carbon atoms can accommodate in contrast to unsaturated hydrocarbons.â¢ Saturated hydrocarbons are the simplest type of hydrocarbons.n unsaturated hydrocarbons, there are double or triple bonds between the carbon atoms. Since there are multiple bonds, the optimal number of hydrogen atoms is not there in the molecule. Alkenes and alkynes are examples for unsaturated hydrocarbons.
