Chapter 21, Problem 21E

Interpretation Introduction

Interpretation:

The structural diagrams of $1,1,1-\text{trichloroethane}$ and $1,1,2-\text{trichloroethane}$ is to be drawn.

Concept introduction:

The structural diagram is a simplified model that represents the arrangement of atoms and bonds in a molecule.

In the IUPAC name of an organic compound, the Greek prefix represents the number of the substituents; the numbers before the Greek prefix or substituent represent the position of the substituents. The functional group may be represented as a suffix or as a prefix. Halogens are represented by ‘halo’ prefix. For example: if fluorine is substituted in the hydrocarbon chain, ‘fluoro’ prefix is used. The suffix for an alkane is ‘ane.

The number of carbon atoms in the parent hydrocarbon chain is represented by the root name. For example: ‘prop’ represent three carbon atoms in the parent hydrocarbon chain.
