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 ...
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-2,3-diol. Other names 2,3-Dimethyl-2,3-butanediol ... Density: 0.967 g/cm 3: Melting point: 40 to 43 °C (104 to 109 °F; 313 to 316 K)
Most famously, at least in the classroom, pinacolone arises by the pinacol rearrangement, which occurs by protonation of pinacol (2,3-dimethylbutane-2,3-diol). [4] Industrially pinacolone is made by the hydrolysis of 4,4,5-trimethyl-1,3-dioxane, which is the product of isoprene and formaldehyde via the Prins reaction.
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 ...
Ethanol energy density can be compared with gasoline in heat-of-combustion tables. ... 2,2-dimethylbutane: 93.4 2,3-dimethylbutane: 94.4
Social Security is the U.S. government’s biggest program; as of June 30, 2024, about 67.9 million people, or one in five Americans, collected Social Security benefits.This year, we’re seeing a ...
Pinacolyl alcohol (also known as 3,3-dimethylbutan-2-ol and as pine alcohol) is one of the isomeric hexanols and a secondary alcohol. Pinacolyl alcohol appears on the List of Schedule 2 substances of the Chemical Weapons Convention as a precursor for the nerve agent soman .
