2,5-Dimethylhexane

Description:
2,5-Dimethylhexane is an organic compound classified as an alkane, specifically a branched-chain hydrocarbon. Its molecular formula is C8H18, indicating it consists of eight carbon atoms and eighteen hydrogen atoms. This compound features a hexane backbone with two methyl groups attached to the second and fifth carbon atoms. 2,5-Dimethylhexane is a colorless liquid at room temperature and is known for its relatively low viscosity and high volatility. It is insoluble in water but soluble in organic solvents, making it useful in various industrial applications, including as a solvent and in fuel formulations. The compound has a relatively high octane rating, which makes it a desirable component in gasoline blends to improve combustion efficiency. Additionally, 2,5-dimethylhexane exhibits typical alkane characteristics, such as being non-polar and having a low reactivity under standard conditions. Its physical properties, such as boiling and melting points, are influenced by its molecular structure and branching, which reduce the surface area and intermolecular forces compared to straight-chain alkanes.
