Chapter 21, Problem 28E

Interpretation Introduction

Interpretation:

A structural diagram of $\text{1-bromo-3-methylcyclohexane}$ 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 number before the substituent represents the position of the substituent. 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. If two or more substituents are present in the compound, then they are named in the alphabetical order.

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. In the case of a cyclic compound, ‘cyclo’ is used before the root name.

When an alkyl group and halogen are present as substituents, the carbon atoms are numbered from halogens.
