Chapter 11, Problem 11.31UKC

Interpretation Introduction

Interpretation:

The structure of the three constitutional isomers that have chlorine atom and an amine group bonded to a benzene ring has to be drawn and IUPAC name for each isomer has to be assigned.

Concept Introduction:

Nomenclature of Benzene derivatives:

• First identify the number of substituent present in the benzene ring.
• If benzene ring has only one substituent, then name the substituent and add this word to benzene.
• If benzene ring has two substituent, then prefix ortho(1,2), meta(1,3), para(1,4) are used to locate the position of the substituent and ortho, meta, para are generally represented as o, m, p respectively.
• If benzene ring has three or more substituent, then the numbering should be given as the lowest possible number around the ring.
• Substituent names should be assigned in alphabetical order.
• If substituent is part of common roots, then the name should be assigned as their derivatives.
