Chapter 21, Problem 49E

Interpretation Introduction

Interpretation:

The following molecule is to be named.

Concept introduction:

To write the IUPAC name of an organic compound that contain a benzene ring, the steps to follow as:

1. Number the carbon atoms present in the benzene ring such that the substituents get the lowest locant number. The carbon atoms are numbered such that the substituents get the lowest possible locant number. If two or more different substituents are present, then the substituents are given preferences according to the IUPAC rule.

2. Specify the substituent position by number the carbon atom to which the substituent is bonded.

3. If there are more substituents in the compound, then they are named according to the alphabetical order.

4. Generally, the base name is benzene for benzene ring. The format to name the molecule that contains a benzene ring is as follows:

$\text{substituent number-substitutent namebenzene}$
