Nomenclature of Heptane Isomers

The International Union of Pure and Applied Chemistry (IUPAC) has established a set of rules for naming alkanes, including heptane. These rules ensure that alkanes are named consistently and unambiguously.

To name an alkane, the following steps are followed:

1. Identify the parent chain. The parent chain is the longest continuous chain of carbon atoms in the molecule.
2. Number the carbon atoms in the parent chain. The carbon atoms are numbered from one end of the chain to the other, starting with the end that gives the lowest numbers to the substituents.
3. Identify the substituents. Substituents are atoms or groups of atoms that are attached to the parent chain.
4. Name the substituents. Substituents are named according to the IUPAC rules for naming functional groups.
5. Combine the names of the parent chain and the substituents to form the name of the alkane.

For example, the following are the IUPAC names of the different structural isomers of heptane:

• Heptane
• 2-Methylhexane
• 3-Methylhexane
• 4-Methylhexane
• 2,2-Dimethylpentane
• 2,3-Dimethylpentane
• 2,4-Dimethylpentane
• 3,3-Dimethylpentane
• 3,4-Dimethylpentane
• 2,2,3-Trimethylbutane

Physical and Chemical Properties of Heptane Isomers

The physical and chemical properties of the different structural isomers of heptane vary depending on their structure.The physical properties of the isomers are primarily determined by their molecular shape and size. The more compact the molecule, the higher its density and boiling point.

The isomers with the most compact structures, such as 2,2-dimethylpentane and 3,3-dimethylpentane, have higher densities and boiling points than the isomers with less compact structures, such as n-heptane and 2-methylhexane.The chemical properties of the isomers are primarily determined by the location of the functional groups.

The isomers with functional groups in more reactive positions are more reactive than the isomers with functional groups in less reactive positions. For example, 2-methylhexane is more reactive than n-heptane because the methyl group in 2-methylhexane is in a more reactive position than the methyl groups in n-heptane.

Boiling Points

• n-Heptane: 98.4 °C
• 2-Methylhexane: 90.0 °C
• 3-Methylhexane: 91.9 °C

• 2,3-Dimethylpentane: 89.8 °C
• 2,4-Dimethylpentane: 80.9 °C
• 3,3-Dimethylpentane: 86.1 °C

Densities

• n-Heptane: 0.68 g/mL
• 2-Methylhexane: 0.67 g/mL
• 3-Methylhexane: 0.68 g/mL
• 2,2-Dimethylpentane: 0.69 g/mL
• 2,3-Dimethylpentane: 0.69 g/mL
