Therefore, neopentane is a gas at room temperature and atmospheric pressure, while the other two isomers are (barely) liquids. The melting point of neopentane (−16.6 °C), on the other hand, is 140 degrees higher than that of isopentane (−159.9 °C) and 110 degrees higher than that of n -pentane (−129.8 °C).
Butlerov's student V. Goryainov originally discovered neohexane in 1872 by cross-coupling of zinc ethyl with tert-butyl iodide. [5]2,2-Dimethylbutane can be synthesised by the hydroisomerisation of 2,3-dimethylbutane using an acid catalyst.
Neopentyl alcohol can be prepared from the hydroperoxide of diisobutylene. [3] It can also be prepared by the reduction of trimethylacetic acid with lithium aluminium hydride.

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 ...
n-Butane, like all hydrocarbons, undergoes free radical chlorination providing both 1-chloro- and 2-chlorobutanes, as well as more highly chlorinated derivatives. The relative rates of the chlorinations are partially explained by the differing bond dissociation energies : 425 and 411 kJ / mol for the two types of C-H bonds.
Samples are typically handled with air-free techniques. Most chemical reactions of nickelocene are characterized by its tendency to yield 18-electron products with loss or modification of one Cp ring. Ni(C 5 H 5) 2 + 4 PF 3 → Ni(PF 3) 4 + organic products. The reaction with secondary phosphines follows a similar pattern:
Cyclopentane (also called C pentane) [4] is a highly flammable alicyclic hydrocarbon with chemical formula C 5 H 10 and CAS number 287-92-3, consisting of a ring of five carbon atoms each bonded with two hydrogen atoms above and below the plane.
