25dimethylhexane

2,5-Dimethylhexane is an organic compound with the chemical formula C8H18. It is a branched-chain alkane, specifically one of the many isomers of octane. Its structure consists of a six-carbon chain with methyl groups attached to the second and fifth carbon atoms. As a saturated hydrocarbon, it is nonpolar and exhibits properties typical of alkanes, such as being flammable and relatively unreactive under normal conditions. It is insoluble in water but soluble in nonpolar organic solvents.

2,5-Dimethylhexane is typically found as a component in gasoline and other petroleum distillates. It can be synthesized through various organic reactions, including the alkylation of smaller hydrocarbons. Its physical properties, such as boiling point and density, are determined by its molecular structure and intermolecular forces. It exists as a liquid at room temperature and atmospheric pressure. In terms of environmental impact, like other volatile organic compounds, it can contribute to air pollution, particularly in the formation of ground-level ozone.
