Structural Formula of Hexane (n-Hexane)

The structural formula of hexane, also known as n-hexane, is CH3(CH2)4CH3. It consists of a chain of six carbon atoms with 14 hydrogen atoms attached to them. The carbon atoms are arranged in a straight line, and each carbon atom is bonded to two hydrogen atoms except for the two end carbon atoms, which are bonded to three hydrogen atoms.

Homologs of Hexane

Homologs of hexane are compounds that have the same functional group but differ in the number of carbon atoms in their chain. Two homologs of hexane are:

1. Pentane (C5H12): It has a chain of five carbon atoms with 12 hydrogen atoms attached to them. The structural formula of pentane is CH3(CH2)3CH3.

2. Heptane (C7H16): It has a chain of seven carbon atoms with 16 hydrogen atoms attached to them. The structural formula of heptane is CH3(CH2)5CH3.

Isomers of Hexane

Isomers of hexane are compounds that have the same molecular formula but differ in the arrangement of atoms. Two possible isomers of hexane are:

1. 2-Methylpentane: It has a chain of five carbon atoms with a methyl group (-CH3) attached to the second carbon atom. The structural formula of 2-methylpentane is CH3CH(CH3)CH2CH2CH3.

2. 3-Methylpentane: It has a chain of five carbon atoms with a methyl group (-CH3) attached to the third carbon atom. The structural formula of 3-methylpentane is CH3CH2CH(CH3)CH2CH3.

Please note that there are several other possible isomers of hexane, but these are two examples.
