2,3,4 trimethylpentane structure

Tetramethylbutane (H3C-)3C-C(-CH3)3 is a hydrocarbon with the formula C8H18, also known as hexamethylethane. It is the only octane isomer with a butane (C4) backbone, and it is the most strongly branched and lightweight of the many octane isomers. It has a very high melting point and a short liquid range due to its highly symmetrical structure; in reality, it is the smallest saturated acyclic hydrocarbon that appears as a solid at room temperature of 25 °C. (Cubane, C8H8, is also smaller and solid at room temperature among cyclic hydrocarbons.)
The compound can be made by reacting tert-butylmagnesium bromide with ethyl bromide or ethylmagnesium bromide with tert-butylmagnesium bromide in the presence of manganese(II) ions with the Grignard reagent tert-butylmagnesium bromide.
[two] The dimerization of two tert-butyl radicals formed by the decomposition of the organomanganese compounds generated in situ is thought to be responsible for this transformation.

At substrate pressures of 1-25 Torr and conversions of 0.03-0.3 percent, 2,2,3,3-tetramethylbutane was photolyzed at 123.6 and 147 nm. Both molecular and free-radical processes are involved in the primary processes. The presence of four essential primary processes is demonstrated by the use of free-radical scavengers oxygen, nitric oxide, and hydrogen sulphide (1). (4). Another primary process that produces molecular methane occurs at 147 nm. The I am ? 3CCMe3*? (1) C4H8 + C4H10 C6H14 + 2Me = C6H14 + 2Me = C6H14 + 2Me = C6H14 C3H6 + Me + Bu (3) = C3H6 + Me + Bu (3) = C3H6 + Me + Bu (3) = C The photolysis process of C 4H8 + H + Bu (4) requires a large number of free radicals and acts similarly to neopentane in this regard.

In the presence of oxygen, the decomposition of 2,2,3,3-tetramethylbutane (TMB) in the temperature range 420–540°C produces 98 percent isobutene through reactions (4) and (5). (5). 2(CH3)3C (CH3)3C (CH3)3C (CH3)3C (CH3)3C (CH3)3C (CH3)3C (CH3)3C (4). (CH3)3C + O2=(CH3)2CCH2+ HO2 (CH3)3C + O2=(CH3)2CCH2+ HO2 (CH3)2CCH2 (5). There is also around 1% isobutane produced, and the rate of isobutane formation at a given temperature is directly proportional to [TMB], and is unaffected by [O2], N2 addition, or vessel diameter. It is shown that these outcomes necessitate a molecular reaction (3). (CH3)3 CC(CH3)3=(CH3)3 CH +(CH3)2 CCH2=(CH3)3 CH +(CH3)2 CCH2 (3). Over the temperature range of 420–540°C, log10(A3/s– 1)= 13.89 0.10, E3= 275 1.4 kJ mol– 1, log10(A3/s– 1)= 13.89 0.10, log10(A3/s– 1)= 13.89 0.10, log10(A3/s– 1)= 13.89 0.10, log10(A3/s– 1)= 13.89 A four-centre transition state is consistent with the A factor.

A molecule’s chemical structure is made up of the arrangement of atoms as well as the chemical bonds that keep them together. There are 25 bonds in the 2,2,3,3-TETRAMETHYLBUTANE molecule (s) There are 7 non-H bond(s) and 1 rotatable bond(s) in this structure (s).
The skeletal formula, which is the regular notation for organic molecules, is also known as the 2D chemical structure picture of 2,2,3,3-TETRAMETHYLBUTANE. The hydrogen atoms attached to carbon atoms are not indicated in the chemical structure of 2,2,3,3-TETRAMETHYLBUTANE; each carbon atom is assumed to be connected with enough hydrogen atoms to provide the carbon atom with four bonds.
The ball-and-stick model is used to represent both the three-dimensional location of the atoms and the bonds between them in the 3D chemical structure picture of 2,2,3,3-TETRAMETHYLBUTANE. To provide a better view of the atoms and bonds in the chemical structure model of 2,2,3,3-TETRAMETHYLBUTANE, the spheres’ radius is smaller than the rod lengths.
