N-Hexane, Hexane CH3(CH2)4CH3 or C6H14

Hexane is an alkane hydrocarbon with the chemical formula CH3(CH2)4CH3 or C6H14. The "hex" prefix refers to its six carbons, while the "ane" ending indicates that its carbons are connected by single bonds. Hexane isomers are largely unreactive, and are frequently used as an inert solvent in organic reactions because they are very non-polar. They are also common constituents of gasoline and glues used for shoes, leather products, and roofing. Additionally, it is used in solvents to extract oils for cooking and as a cleansing agent for shoe, furniture and textile manufacturing. In laboratories, hexane is used to extract oil and grease from water and soil before determination by gravimetric analysis or gas chromatography Hexane is produced by the refining of crude oil. The exact composition of the fraction depends largely on the source of the oil (crude or reformed) and the constraints of the refining. The industrial product (usually around 50% by weight of the straight-chain isomer) is the fraction boiling at 65–70 °C

Isomers

Hexane has five isomers:
**Hexane, CH3CH2CH2CH2CH2CH3, a straight chain of six carbon atoms.
**2-Methylpentane (Isohexane), CH3CH(CH3)CH2CH2CH3, a five-carbon chain with one methyl branch on the second.http://www.thchemicals.blogspot.com, http://thchemicals.com, http://dungmoi.com
**3-Methylpentane, CH3CH2CH(CH3)CH2CH3, a five-carbon chain with one methyl branch on the third. http://www.thchemicals.blogspot.com, http://thchemicals.com, http://dungmoi.com
**2,3-Dimethylbutane, CH3CH(CH3)CH(CH3)CH3, a four-carbon chain with one methyl branch on the second and third.
**2,2-Dimethylbutane (neohexane) , CH3C(CH3)2CH2CH3, a four-carbon chain with two methyl branches on the second.
