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.

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 ...
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.
2,2-Dimethylbutane, trivially known as neohexane at William Odling's 1876 suggestion, [4] is an organic compound with formula C 6 H 14 or (H 3 C-) 3-C-CH 2-CH 3. It is therefore an alkane , indeed the most compact and branched of the hexane isomers — the only one with a quaternary carbon and a butane (C 4 ) backbone.

Pentaerythritol was first reported in 1891 by German chemist Bernhard Tollens and his student P. Wigand. [5] It may be prepared via a base-catalyzed multiple-addition reaction between acetaldehyde and 3 equivalents of formaldehyde to give pentaerythrose (CAS: 3818-32-4), followed by a Cannizzaro reaction with a fourth equivalent of formaldehyde to give the final product plus formate ion.
c 6 h 5 c(ch 3) 2 ch 2 oh + socl 2 → c 6 h 5 c(ch 3) 2 ch 2 cl + hcl + so 2 It is easily prepared on a large scale from benzene and methallyl chloride by an electrophilic aromatic substitution reaction, using sulfuric acid as the catalyst : [ 4 ] The reaction is an example of an electrophilic aromatic substitution reaction.
