Whether the Lewis diagram of HCN is acceptable or unacceptable is to be predicted. The reason for acceptability or unacceptability of the Lewis diagram is to be stated. The acceptable Lewis diagram of HCN is to be drawn. Concept introduction: Lewis diagram is a representation of the chemical formula of substance with valance electrons of atoms. The Lewis structures are also known as electron dot structures. In the Lewis structure, electrons are denoted by dots. Only the valence electrons are presented as dots in the Lewis structure.

Question

Consider the molecules of furan and benzene. The dominant Lewis structure of furan and the two resonance structures of benzene are shown below: H K Book H What is the meaning of the double-sided arrow () connecting the two structures of benzene? Furan Benzene H It indicates that electrons in benzene rapidly change their positions corresponding to the two structures. It indicates that there are two independent coexisting forms of benzene. It indicates a chemical equilibrium between the two distinct structures. It indicates that the second structure can be obtained as a mirror image of the first one. It indicates that benzene exists in a single form, which is an average of the two structures.
