Chapter F, Problem F.28P

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 naming ester, the alkyl group is cited first, followed by the carboxylate group separated by a space. Thus, the general form of an ester name is alkyl alkanoate. The alkyl group bonded to the oxygen atom in ester and alkanoate is the part of carbonyl group. The alkan is the root name, and the suffix oate is added to the root name for the functional group ester.

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.
