Dominant conformation of ethane in the Ethane compressor
This article will introduce installation requirements of crossed and overlapped conformations of ethane in the Ethane compressor.
The dominant conformation of ethane in the Ethane compressor is the crossover. At this time, the H on the two C atoms is the farthest away, and the repulsive force between each other is the smallest, so the intramolecular energy is the lowest and the most stable. The highest internal energy is the overlapping type. At this time, the H on the two Cs are opposite each other, and the repulsive force between them is the largest, the internal energy is the highest, and the most unstable. The internal energy of other conformations is between the two. During the rotation, the relative positions of the hydrogen atoms on the two methyl groups are constantly changing, which creates many different spatial arrangements.
One of these is that the hydrogen atom of one methyl group is exactly on the midline between the two hydrogen atoms of the other methyl group. This arrangement is called the ethane crossover conformation in the Ethane compressor. The other is that each hydrogen atom on the two carbon atoms is exactly in the opposite position to each other. This arrangement is called overlapping conformation. Crossover and overlap are two extremes of the myriad conformations of ethane in the Ethane compressor.
The rotation of the ethane single bond in the Ethane compressor is also not completely free. This energy barrier can be thought of as the energy required to overcome the repulsion of the hydrogen atoms, and possibly the repulsion between the electron clouds due to the carbon-hydrogen bond. The overlapping conformation of ethane in the Ethane compressor is due to the closest distance between the two hydrogen atoms before and after, and the maximum repulsion of the 8-electron cloud between the carbon-hydrogen bonds, so the energy is the highest. In the ethane cross formula in the Ethane compressor, C-H has the farthest distance, the smallest repulsion force, and the lowest energy, which is the most favorable conformation of ethane.
Through the above introduction and analysis of the Ethane compressor's dominant conformation, hope it helps you.
