Interpretation Introduction

(a)

Interpretation: The structure corresponding to given IUPAC name of a compound is to be drawn.

Concept introduction: IUPAC nomenclature is a systematic way of naming the organic compounds. The basic principles of IUPAC naming for benzene derivatives are:

1. When the ring is mono-substituted, then there is no need of numbering.

2. When the ring is substituted with same substituents, then numbering to one substituent is given and for other substituent, numbering proceed from clockwise or anticlockwise such that it gets lower number.

3. When the ring is substituted with different substituents, then the numbering is done on the basis of priority.

4. Substituents on benzene ring is also indicated using ortho, meta, para prefix. The prefix ortho is used when substituents are on adjacent carbon, meta is used when substituents are separated by one carbon atom, para is used when substituents are across each other in benzene ring.
