How many isomers does hexane have?

Hexane can form five isomers with its six carbon bonds. The five isomers are 2-methylpentane, 3-methylpentane, 2,2-dimethylbutane, 2,3-dimethylbutane and hexane itself, which is a straight chain of six carbon atoms.

Hexane isomers are generally unreactive and non-polar, and they are commonly used as an inert solvent in organic reactions. Isomers are commonly found in gasoline or glues and can be used in leather products. Hexane isomers can also be used to extract grease or oil from water and soil.

Hexane is created by refining crude oil. Its composition is dependent on how thoroughly it's refined, as well as the quality of the oil product itself.
