Isomers are the organic compounds having same molecular formula, but different arrangements of carbon atoms or simply different structures. For example, butane can exist in two isomeric forms such as n-butane and iso-butane.

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 .
