Interpretation Introduction

(a)

Interpretation: The structure which corresponds to the IUPAC name of the given compound is to be stated.

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

1. The compound consists of benzene ring is named as substituent followed by benzene.

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

3. 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.

4. When the ring is substituted with different substituents, then the numbering is done according to the priority.

5. 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.

Answer to Problem 17.28P

The structure of the given compound is,
