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.

2,3-Dimethylbutane Names Preferred IUPAC name. 2,3-Dimethylbutane [1] ... 2,3-Dimethylbutane is an isomer of hexane. It has the chemical formula (CH 3) 2 CHCH(CH 3) 2 ...
For example, (CH 3) 2 CHCH 3, commonly known as isobutane, is treated as a propane chain with a methyl group bonded to the middle (2) carbon, and given the systematic name 2-methylpropane. However, although the name 2-methylpropane could be used, it is easier and more logical to call it simply methylpropane – the methyl group could not ...
Tetramethylbutane, sometimes called hexamethylethane, is a hydrocarbon with formula C 8 H 18 or (H 3 C-) 3 C-C(-CH 3) 3.It is the most heavily branched and most compact of the octane isomers, the only one with a butane (C4) backbone.
The traditional name neopentane, coined by William Odling in 1876, [5] was still retained in the 1993 IUPAC recommendations, [6] [7] but is no longer recommended according to the 2013 recommendations. [2] The preferred IUPAC name is the systematic name 2,2-dimethylpropane, but the substituent numbers are superfluous because it is the only ...
For example, compare isobutane (2-methylpropane) and n-butane (butane), which boil at −12 and 0 °C, and 2,2-dimethylbutane and 2,3-dimethylbutane which boil at 50 and 58 °C, respectively. [ 18 ] On the other hand, cycloalkanes tend to have higher boiling points than their linear counterparts due to the locked conformations of the molecules ...
2,2-Dimethylpentane can form a clathrate hydrate with helper gas molecules. The type of clathrate formed is called "clathrate H". 2,2-Dimethylpentane was the first compound for which the structure was determined. The clathrate has 34 molecules of water per molecule, and also has xenon and hydrogen sulfide as helper molecules.
