Chapter E, Problem E.3P

Interpretation Introduction

(a)

Interpretation:

The complete IUPAC name of the given molecule is to be written.

Concept introduction:

To write the IUPAC name, first, it is important to determine the highest-priority functional group present that requires a suffix referring to Table E-1. For a molecule that contains a ${\text{NH}}_2$ as the highest priority group, the amine suffix is added to the IUPAC name of the root chain. The next step is to number the main chain or ring such that carbon atoms involving the highest-priority functional group receive the lowest possible numbers. The locator number for the highest-priority functional group is written immediately before the suffix, except when redundant. All other functional groups in the molecule are treated as substituents and appear in the name as a prefix. Prefixes such as ‘di’, ‘tri’, ‘tetra’… etc. are used to indicate the number of identical substituents attached. The substituents are named in the alphabetical order.
