Density: 662 mg mL −1: Melting point: −136 to −124 °C; −213 to −191 °F; 137 to 149 K ... 2,3-Dimethylbutane is an isomer of hexane. It has the chemical ...
Dimethylbutadiene, formally referred to as 2,3-dimethyl-1,3-butadiene, is an organic compound with the formula (CH 3) 2 C 4 H 4. It is colorless liquid which served an important role in the early history of synthetic rubber. It is now a specialty reagent.
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 ...
The gauche effect is very sensitive to solvent effects, due to the large difference in polarity between the two conformers.For example, 2,3-dinitro-2,3-dimethylbutane, which in the solid state exists only in the gauche conformation, prefers the gauche conformer in benzene solution by a ratio of 79:21, but in carbon tetrachloride, it prefers the anti conformer by a ratio of 58:42.

Figure 5 shows 2-chloro-2,3-dimethylbutane in a sawhorse projection with chlorine and a hydrogen anti-periplanar to each other. Syn-periplanar or synperiplanar is similar to anti-periplanar. In the syn-periplanar conformer, the A and D are on the same side of the plane of the bond, with the dihedral angle of A−B and C−D between +30° and ...

2,3-Dimethyl-1-butene is an organic compound with the formula CH 2 =C(CH 3)CH(CH 3) 2. Like the other isomers of dimethylbutene, it is a colorless liquid. Together with 2,3-dimethyl-2-butene it can be produced by dimerization of propylene. It is a precursor to the commercial fragrance tonalide. [1]
