What are the isomers of octane?

Answer by  IloveScience (118)

Octane has many isomers include: n-octane(no substituents, octane), methylheptane(e.g. 2-methylheptane), ethylhexane(e.g. 3-ethyl hexane), dimethylhexane(e.g. 2,3dimethylhexane), trimethylpentane(e.g. 2,2,3trimethylpentane) and ethylmethylpentane(e.g. 4-ethyl3-methylpentane).

There are eighteen different isomers of octane however they all have one thing in common. For a compund to be considered octane, it must have a total of eight carbon atoms joined by single bonds between each carbon atom. These carbons may be in the form of a long chain or a shorter chain with carbons attached to the sides.
