Nomenclature of organic compounds

[Vernii]

TL;DR

Help me understand the following excerpt :-

It is very important to recognize that, in general, the rules of the nomenclature of organic compounds are written in terms of classical valence bonding and do not imply electronic configurations of any kind.

The replacement operation can be used for naming organic compounds in which skeletal atoms of a parent structure are replaced by other skeletal atoms, or in which oxygen atom and/or hydroxy groups of characteristic groups are replaced by other atoms or groups.

It is very important to recognize that, in general, the rules of organic nomenclature are written in terms of classical valence bonding and do not imply electronic configurations of any kind.

Examples of naming structures in several ways are shown in Table 1.

It means that the name won’t reflect electronic tendencies like electronegativity.

CH₂Cl₂ would be dichloromethane rather than methane dichloride or methylene chloride or methylene dichloride (implying the chlorine exists as Cl^-).
