Saturated hydrocarbons are carbon compounds with only single bonds between the carbon atoms and the valencies are satisfied by hydrogen atoms. Alkanes are saturated hydrocarbons with the general formula C n H 2 n + 2 and the compound ethane with the formula C 2 H 6 is the second member of the alkane series. Unsaturated hydrocarbons are hydrocarbons with multiple bonds such as double or triple bonds between the adjacent carbon atoms. Alkynes with the formula C n H 2 n + 2 is an example of unsaturated hydrocarbons. Ethyne C 2 H 2 ⇔ HC ≡ CH with a triple bond is the first member of the alkyne series. A group of atoms present in a molecule which is responsible for the characteristic chemical properties of an organic compound is termed as a functional group. The functional group present in CH 4 O ⇔ CH 3 OH is alcohol, - OH group. Unsaturated hydrocarbons are hydrocarbons with multiple bonds such as double or triple bonds between the adjacent carbon atoms. Alkenes with the formula C n H 2 n is an example of unsaturated hydrocarbons. Propene with the formula C 3 H 6 ⇔ H 3 C - HC = CH 2 is the second member of the alkene series. Column A Column B a.
