Conformations of 1 - bromo - 2 - chloroethane
The conformation of 1-bromo-2-chloroethane
The conformation of an organic organism is related to the morphology and properties of molecules. The conformation of 1-bromo-2-chloroethane (1-bromo-2-chloroethane) is important for the study of real chemistry.
1-bromo-2-chloroethane is connected by its carbon chain, and bromine and chlorine occupy different carbon sites. The conformational change originates from the rotation of the carbon-carbon single bond. When the single bond rotates, the spatial arrangement of the atoms in the molecule also changes, resulting in different conformations.
Its main conformations are anti-conformation and gauche-conformation. In the counter-conformation, bromine and chlorine are as far away as possible in space, the interaction is the weakest, and the system energy is the lowest and most stable. In this conformation, the repulsion between atoms is small, just like the intersection of gentlemen, harmonious and different, each in its own position. In the ortho-conformation, bromine and chlorine are closer, there is a certain repulsion, and the energy is slightly higher than that of the counter-conformation.
There is also an eclipsed-conformation, in which bromine and chlorine are in the overlapping position, the repulsion between atoms is the largest, the energy is the highest, and the stability is the worst. This situation is like two cars meeting on a narrow road, crowded and difficult to survive for a long time.
The study of the conformation of 1-bromo-2-chloroethane is of great significance for organic synthesis and the investigation of the reaction mechanism. By regulating the reaction conditions, the molecules can be inclined to a specific conformation, which in turn affects the direction and rate of the reaction. Knowing the wonders of conformation is like grasping the cardinal of chemical change, and it has made great contributions to the development of organic chemistry.
