Chapter 4, Problem 48P

Interpretation Introduction

Interpretation:

IUPAC names of the given compounds are to be given, using rules found in the chapter or more rules need to be provided are to be indicated.

Concept introduction:

IUPAC nomenclature is a systematic method for naming organic compounds.

$E-Z$ Configuration is used to designate alkene diastereomers (cis-trans isomers).

First, give priority according to Cahn-Ingold-Prelog convention rules:

The higher the atomic mass, the higher will be its priority.

If priority cannot be assigned according to atomic mass, then assign priority according to the first point of difference.

If both the priority groups are on the same side of a double-bonded carbon atom, then it is known as $\left(Z\right)$ configuration.

If both the priority groups are diagonal to each other, then it is $\left(E\right)$ configured.
