2-Methyloctane

Description:
2-Methyloctane is an organic compound classified as an alkane, specifically a branched-chain hydrocarbon. Its molecular formula is C9H20, indicating it consists of nine carbon atoms and twenty hydrogen atoms. This compound features a methyl group attached to the second carbon of an octane chain, which contributes to its branched structure. 2-Methyloctane is a colorless liquid at room temperature and is typically insoluble in water due to its nonpolar nature, but it is soluble in organic solvents. It has a relatively high boiling point compared to straight-chain alkanes of similar molecular weight, which is a characteristic of branched alkanes due to their lower surface area and reduced van der Waals forces. 2-Methyloctane is used in various applications, including as a component in fuels and lubricants, and it may also serve as a solvent in chemical processes. Its properties make it relevant in studies of hydrocarbon behavior and in the formulation of gasoline blends to improve octane ratings.
