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 many octane isomers, the only one with a butane (C4) backbone. Because of its highly symmetrical structure, it has a very high melting point and a short liquid range ...
In chemistry, 2,2,3,3-tetramethylsuccinic acid or 2,2,3,3-tetramethylbutane-1,4-dioic acid is a dicarboxylic acid with the formula C 8 H 14 O 4, or HOOC-C(CH 3) 2-C(CH 3) 2-COOH. It can be seen as derivative of succinic acid (butane-1,4-dioic acid) with two methyl groups replacing two hydrogen atoms on each of the central carbon atoms of the chain.
Triptane, or 2,2,3-trimethylbutane, is an organic chemical compound with the molecular formula C 7 H 16 or (H 3 C-) 3 C-C (-CH 3) 2 H. It is therefore an alkane, specifically the most compact and heavily branched of the heptane isomers, the only one with a butane (C 4) backbone. Triptane is commonly used as an anti-knock additive in aviation ...

Eclipsed conformation. In chemistry an eclipsed conformation is a conformation in which two substituents X and Y on adjacent atoms A, B are in closest proximity, implying that the torsion angle X–A–B–Y is 0°. [1] Such a conformation can exist in any open chain, single chemical bond connecting two sp 3 - hybridised atoms, and it is ...
2,3-Dimethylpentane is notable for being one of the two simplest alkanes with optical (enantiomeric) isomerism. The optical center is the middle carbon of the pentane backbone, which is connected to one hydrogen atom, one methyl group, one ethyl group – C. 2H. 5, and one isopropyl group – CH (CH. 3)
