Pentane is an organic compound with the formula C 5 H 12 —that is, an alkane with five carbon atoms. 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, in which case pentanes refers to a mixture of them; the other two are called isopentane (methylbutane) and neopentane ...
Constitution formula for isomers of C 5 H 8 with CAS numbers. The molecular formula C 5 H 8 may refer to any of the following hydrocarbons: . Pentynes:; 1-Pentyne; 2-Pentyne; 3-Methyl-1-butyne or isopentyne, CAS 598-23-2
Drifting smoke particles indicate the movement of the surrounding gas.. Gas is one of the four fundamental states of matter.The others are solid, liquid, and plasma. [1] A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).
Cycloalkanes are also called naphthenes. [11] [12] Branched-chain alkanes are called isoparaffins. "Paraffin" is a general term and often does not distinguish between pure compounds and mixtures of isomers, i.e., compounds of the same chemical formula, e.g., pentane and isopentane. In IUPAC. The following trivial names are retained in the IUPAC ...
Petroleum ether should not be confused with the class of organic compounds called ethers; and equally, going under its alternative name of benzine, it should not be confused with benzene. (Benzine is a mixture of alkanes, such as pentane, hexane, and heptane; whereas benzene is a cyclic, aromatic hydrocarbon.)
Neopentane, also called 2,2-dimethylpropane, is a double-branched-chain alkane with five carbon atoms. Neopentane is a flammable gas at room temperature and pressure which can condense into a highly volatile liquid on a cold day, in an ice bath, or when compressed to a higher pressure.

It was called vinyltrimethylene in the initial publication. [8] In 1907, Fecht expressed the assumption that it must be spiropentane, a constitutional isomer of vinylcyclopropane. [ 9 ] Further evidence for the structure of the hydrocarbon comes from the fact that it could also be obtained from 1,1-bis(bromomethyl)-cyclopropane (see formula ...
