Hexane (/ ˈ h ɛ k s eɪ n /) or n-hexane is an organic compound, a straight-chain alkane with six carbon atoms and the molecular formula C 6 H 14. [7]Hexane is a colorless liquid, odorless when pure, and with a boiling point of approximately 69 °C (156 °F).
2-Methylpentane, trivially known as isohexane, is a branched-chain alkane with the molecular formula C 6 H 14.It is a structural isomer of hexane composed of a methyl group bonded to the second carbon atom in a pentane chain.
3-Methylpentane is a branched alkane with the molecular formula C 6 H 14.It is a structural isomer of hexane composed of a methyl group bonded to the third carbon atom in a pentane chain.

The chair and twist-boat are energy minima and are therefore conformers, while the half-chair and the boat are transition states and represent energy maxima. The idea that the chair conformation is the most stable structure for cyclohexane was first proposed as early as 1890 by Hermann Sachse, but only gained widespread acceptance much later.
Benzene is converted to cyclohexylbenzene by acid-catalyzed alkylation with cyclohexene. [6] Cyclohexylbenzene is a precursor to both phenol and cyclohexanone. [7]Hydration of cyclohexene gives cyclohexanol, which can be dehydrogenated to give cyclohexanone, a precursor to caprolactam.
In organic chemistry, benzyl is the substituent or molecular fragment possessing the structure R−CH 2 −C 6 H 5. Benzyl features a benzene ring ( C 6 H 6 ) attached to a methylene group ( −CH 2 − ).
