Chapter 25, Problem 23QP

Interpretation Introduction

Interpretation:

The given molecular models are to be converted into a condensed structural formula, a Kekule structure, and a skeletal (line) structure.

Concept Introduction:

Molecular model of a chemical compound represents the three-dimensional position of the atoms along with the bonds between them. The atoms are represented by spheres, connected by rods, which represent the bonds.

Wedges represent the bonds toward the viewer, dashes represent the bonds away from the viewer, and solid lines represent the bonds in the plane of the image.

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 an atom 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 a single line or branched chains; it is called the condensed structural formula.

In an organic molecule, when the structure consists of straight lines that represent $\text{C}-\text{C }$ bonds in which carbon and hydrogen atoms are not shown, it is called skeletal structures.
