2,3-Dimethylbutane Skeletal formula of 2,3-dimethylbutane with some implicit hydrogens shown: ... Melting point: −136 to −124 °C; −213 to −191 °F; 137 to ...
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.
The melting point of neopentane (−16.6 °C), on the other hand, is 140 degrees higher than that of isopentane (−159.9 °C) and 110 degrees higher than that of n-pentane (−129.8 °C). This anomaly has been attributed to the better solid-state packing assumed to be possible with the tetrahedral neopentane molecule; but this explanation has ...
Dimethylbutadiene readily undergoes Diels-Alder reactions and reacts faster than 1,3-butadiene.Its effectiveness in this reaction is attributed to the stabilization of the cis-conformation owing to the influence of the methyl groups on the C2 and C3 positions.
Pinacolone (3,3-dimethyl-2-butanone) is an important ketone in organic chemistry.It is a colorless liquid with a slight peppermint or camphor odor. It is a precursor to triazolylpinacolone in the synthesis of the fungicide triadimefon and in synthesis of the herbicide metribuzin.
Critics of a US sovereign wealth fund point out that the US, far from having a surplus, runs trillion-dollar deficits — the opposite of the world's largest SWFs. Absent a surplus, the money ...
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.
But you can also use blood testing to determine biological age, he points out. And based on the study results, it seems like this is the best way to go if you want a really accurate answer.
