Chapter 1, Problem 1.16P

Interpretation Introduction

Interpretation:

To draw two different three-dimensional representations for CH₂Cl₂ (dichloromethane) using wedges and dashes

Concept introduction:

In the stereochemistry, various methods are depicted to represent three dimensional representations. Methane, a tetrahedral model, substituted by four different or same types of ligands at the vertices of the tetrahedron, which is not apparent in the chemical bonding. Thus to represent it in another form of representations and to understand it in well. A new form of representations is used. Wedge and dashed lines.

Wedge or solid heavy line represent a bond that project above the plane or pointing towards the observer. Broken wedge or dashed lines are that project below the plane or pointing away from the observer. The wedge and dashed lines for the sample methane is shown below in the Fig.1. Structure A and B represent a normal structure. Structure C represent the wedge and dashed lines. In the Structure C, a represent wedge, b represent dashed lines and c, d represent solid lines.
