Hydrocarbon cells explain that compounds of carbon and hydrogen only. They are used for the manufacture of polymers like polyethylene, polytropon, polystyrene etc. Fuels contain a mixture of hydrocarbons which are sources of energy. Hydrocarbons are classified on the basis of carbon-carbon bonds present and they are categorised into three types (i) Saturated (alkane) (ii) Unsaturated (alkane) (iii) Aromatic. Alkanes contain carbon-carbon sigma bonds and the important reactions of alkanes are free radical substitution, combustion, oxidation and aromatization. Alkene are unsaturated hydrocarbons containing atleast one double bond. Alkenes are manufactured or prepared from alkynes, from vicinal dihalides from alcohol by acidic dehydration alkene and alkynes undergo addition reactions, which are electrophilic addition. Aromatic hydrocarbon known as ‘arenes' and most compounds found to contain benzene rings. Alkane shows conformational isomerism due to free rotation where alkene exhibits geometrical isomerism due to restricted rotation. Polynuclear hydrocarbons having fused benzene systems have carcinogenic properties. The nature of groups or substituents attached to the benzene ring is responsible for activation or deactivation of the benzene ring toward further electrophilic substitution and also orientation of the incoming group.
