We are given Octane which has the chemical formula as C8H18, and we need to find its three possible structures.

Isomerism is defined as the phenomenon in which a chemical compound will consist of the same chemical formula but it will have different orientation or bond arrangements. in simpler meaning isomers of a compound has same chemical formula but has different structures.

Some possible isomers of the compound Octane are given as in terms of their IUPAC names.
