In IUPAC nomenclature however the term pentane is used exclusively for n-pentane, the unbranched isomer of the group. Its electron dot structure is given below. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer; the other two are called isopentane (methylbutane) and neopentane (dimethylpropane).

For physicochemical, thermodynamic, transport, spectra, and other property data & information, the followings are available from “Mol-Instincts”, a chemical database based on quantum mechanics: The SMILES string of PENTANE is CCCCC, which can be can be imported by most molecule editors for conversion back into two-dimensional drawings or three-dimensional models of the PENTANE. Pentane is one of three structural isomers with the molecular formula C 5 H 12, the others being isopentane and neopentane. Usually, a mixture of n-, i-, and increasingly cyclopentane is used for this purpose. Because of their low boiling points, low cost, and relative safety, pentanes are used as a working medium in geothermal power stations in some blended refrigerants also used as a working medium in organic rankine cycles. 2-Methoxypentane. Pentanes are components of some fuels and are employed as specialty solvents in the laboratory. The same tends to be true for the melting points of alkane isomers, and that of isopentane is 30 °C lower than that of n-pentane. Pentane (C 5 H 12) has three structural isomers.. 1.Isomer 1 is n-pentane, the straight chain normal structure for pentane.. 2.Isomer 2 is 2-methylbutane, a branched chain with a carbon* atom joined onto three other carbon atoms.. 3.Isomer 3 is 2,2-dimethylpropane, a branched chain with the central carbon* atom joined onto four other carbon atoms.

Pentane is an organic compound with the formula C5H12—that is, an alkane with five carbon atoms. 3212 Pentanes are relatively inexpensive and are the most volatile liquid alkanes at room temperature, so they are often used in the laboratory as solvents that can be conveniently and rapidly evaporated. However, because of their nonpolarity and lack of functionality, they dissolve only nonpolar and alkyl-rich compounds. However, if heated above 36°C/97°F it becomes a gas, and when cooled it becomes a solid.
