Isomerism in Alkanes

Isomerism is a phenomenon whereby two or more molecules are found to have the same molecular formula, but with different structural formula.

They have different structural formulas, hence different physical properties for example different melting and boiling points.

Isomerism in alkanes must start with molecules that have more than 3 carbon atoms, so methane, ethane and propane do not have isomers.

General formula=CnH2n+1
Isomerism in Butane:

2-methylpropane - Isomer of Butane n-butane - Isomer of Butane
