Concept Introduction:
The structural formula of a chemical compound consists of the graphic representation of the molecular structure and the arrangement of atoms.
In an organic molecule, the structure representation of atoms takes place by single or double bonds without lone pairs;it is called the Kekule structure.
In an organic molecule, bonds are not represented by single lines or branched chains; it is called the condensed structural formula.
In an organic molecule, when the structure consists of straight lines that represent
