Sr. No. Common Name Structural formula IUPAC Name 1 . Ethylene CH 2 = CH 2 Ethene 2 . Acetic acid CH 3 COOH Ethanoic acid 3 . Methyl alcohol CH 3 OH Methanol The IUPAC name of ethylene is ethene. It belongs to the alkene homologous series. It is the first member of the alkene homologous series. In the structure of ethene, there is a double bond present. The common name of ethanoic acid is acetic acid. An aqueous solution of ethanoic acid is called vinegar. It contains a carboxyl functional group – COOH . The structural formula of methanol is CH 3 OH . It contains a hydroxyl – OH functional group. The general formula of alcohol is R - OH , where R is an alkyl group.

Straight chain of Carbon compounds Structural formula Molecular formula Name C CH 4 Methane C - C C 2 H 6 Ethane C - C - C C 3 H 8 Propane C - C - C - C C 4 H 10 Butane Methane, ethane, propane and butane are saturated hydrocarbons containing 1 , 2 , 3 and 4 carbon atoms respectively. Saturated hydrocarbons are the simplest of the hydrocarbon species and are composed entirely of single bonds. All these hydrocarbons belong to the alkane homologous series. The general formula for alkanes is C n H 2 n + 2 . So, the chemical formula for ethane is C 2 H 6 , for propane it is C 3 H 8 and the formula for butane is C 4 H 10 .

Hydrocarbons are a class of organic compounds consisting entirely of hydrogen and carbon. Hydrocarbons are generally colourless and hydrophobic with only weak odours. Hydrocarbons are the principal constituents of petroleum and natural gas. They are used as fuels and lubricants as well as raw materials for the production of plastics, fibres, rubbers, solvents, explosives and industrial chemicals. Methane, ethane, propane, butane, etc., are examples of some common hydrocarbons.
