Write any three possible structures for octane, C8H18,and give their iupac names.

(1) n-Octane

(2) 2-methyl-Heptane

(3) 3-methyl-Heptane

(4) 4-methyl-Heptane

(5) 2-ethyl-Hexane

(6) 3-ethyl- Hexane

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.

Chemical formula : C8H18

(1) n-Octane

(3) 3-methyl-Heptane

(4) 4-methyl-Heptane

(5) 2-ethyl-Hexane

(6) 3-ethyl- Hexane

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
