2-methylhexane

2-Methylhexane is a branched alkane with the chemical formula C₇H₁₆. It is one of the many isomers of heptane. This compound is a hydrocarbon and is part of the alkane family, which are saturated hydrocarbons with single bonds between carbon atoms.

Structure and Properties

2-Methylhexane consists of a six-carbon chain with a methyl group (CH₃) attached to the second carbon atom. The molecular formula is C₇H₁₆, and its molecular weight is 100.20 g/mol. The IUPAC name for this compound is 2-Methylhexane.

Physical Properties

2-Methylhexane is a colorless liquid at room temperature. It has a boiling point of approximately 90-92°C and a melting point of around -118°C. The density of 2-Methylhexane is about 0.68 g/cm³.

Chemical Properties

As a member of the alkane family, 2-Methylhexane is relatively non-reactive. It undergoes typical alkane reactions such as combustion and halogenation. In combustion, it reacts with oxygen to produce carbon dioxide and water. In halogenation, it reacts with halogens like chlorine or bromine in the presence of light or heat to form haloalkanes.

Production and Synthesis

2-Methylhexane can be synthesized through various methods, including the hydrogenation of 2-Methylhexene or by the isomerization of n-heptane in the presence of a catalyst.
