Chapter F, Problem F.29P

Interpretation Introduction

(a)

Interpretation:

The structure for the given trivial name is to be drawn, and the correct IUPAC name is to be written.

Concept introduction:

The trivial names are commonly used names which are not systematic ones. Many trivial names are accepted by IUPAC.

In an amide, the functional group is represented as the carbonyl carbon is bonded to the nitrogen atom as $\text{O=C}-\text{N}$. Thus, the suffix added to the root name is amide. If amide nitrogen is attached to alkyl groups, the italic $N$ is given as the locator to the alkyl substituents instead of a number.

The root name is established by identifying the longest carbon chain or a ring containing the functional group. Remove the e from the normal ane, ene, or yne ending, and add the suffix that corresponds to the highest-priority functional group. Number the carbon chain in a way that the functional group and the substituents attached get the lowest number. The position of the functional group and substituents on the parent chain or ring is indicated by the respective locant number just before the suffix. Prefixes are used to denote the number of identical substituents. The substituents are written in alphabetical order when writing the IUPAC name.
