Answer:
(1) n-Octane
(2) 2-methyl-Heptane
(3) 3-methyl-Heptane
(4) 4-methyl-Heptane
(5) 2-ethyl-Hexane
(6) 3-ethyl- Hexane
Step-by-step explanation:
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.
