Using the Lewis structure of bromoethane ($CH_3CH_2Br $) as the core text, the Lewis structure of

is related to the interatomic bonds and the arrangement of valence electrons. Looking at it, carbon has tetravalent, hydrogen has monovalent, and bromine is heptavalent.

Carbon is related to covalent bonds, the first carbon is connected to trihydrogen and secondary carbon, and the secondary carbon is also connected to dihydrogen and monobromine. In the meantime, carbon and carbon are connected by single bonds, and hydrocarbons and carbon bromide are also maintained by single bonds. Each atom then reaches a stable electronic configuration to form this compound state. The shape of this structure is actually the result of the interaction of electron clouds, and the valence electrons are reasonably distributed between atoms, resulting in specific geometric and chemical properties of molecules.

In this way, the Lewis structure of bromoethane is clear, which is the cornerstone of its chemical behavior and reaction mechanism, and is quite important in the study of organic chemistry.
