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. It is of similar structure to the isomeric 2-methylpentane , which has the methyl group located on the second carbon of the pentane chain.
2,2,4-Trimethylpentane, also known as isooctane or iso-octane, is an organic compound with the formula (CH 3) 3 CCH 2 CH(CH 3) 2.It is one of several isomers of octane (C 8 H 18).This particular isomer is the standard 100 point on the octane rating scale (the zero point is n-heptane).
As of early 1990s, it was present in American [4] and European [5] gasoline in small amounts, and by 2011 its share in US gas varied between 2 and 8%. [6] Using a quantitative structure-activity relationship (QSAR) prediction model, 2-Methylpentane has a research octane number (RON) of 75, motor octane number (MON) of 77, and cetane number (CN ...
Isopentane is a major component (sometimes 30% or more) of natural gasoline, an analog of common petroleum-derived gasoline that is condensed from natural gas. [4] Its share in commercial car fuel is highly variable: 19–45% in 1990s Sweden, [13] 4–31% in 1990s US [14] and 3.6–11% in the US in 2011. [15]
In 1929 Graham Edgar and George Calingaert made 3,3-dimethylpentane and measured its physical characteristics for the first time. The measurements were at 20 °C, not the standard conditions used in later times. [3] For 3,3-dimethylpentane they measured a density of 0.6934 at 20 °C with a rate of change Δd/ΔT of 0.000848.
2,3-Dimethylpentane is notable for being one of the two simplest alkanes with optical (enantiomeric) isomerism. The optical center is the middle carbon of the pentane backbone, which is connected to one hydrogen atom, one methyl group, one ethyl group – C 2 H 5, and one isopropyl group – CH(CH 3) 2.
3-Methyl-3-pentanol (IUPAC name: 3-methylpentan-3-ol) is an organic chemical compound and a tertiary hexanol. It is used in the synthesis of the tranquilizer emylcamate , [ 2 ] and has similar sedative and anticonvulsant actions itself.
2,3,3-Trimethylpentane is a chemical compound in the family of hydrocarbons which has a formula of C 8 H 18. It is an isomer of octane . It has a role as a human metabolite, a bacterial metabolite and a mammalian metabolite. [ 2 ]
