Chapter 5, Problem 47PP

(a)

Interpretation Introduction

Interpretation:

The configuration for every chiral center in the given compound has to be determined.

Concept introduction:

The stereoisomerism is the arrangement of atoms in molecules whose connectivity remains the same but their arrangement in different in each isomer.

Chiral centre: A chiral centre is defined as the tetrahedral carbon atom in an organic molecule that is connected to four non-identical groups/substituents. It is known as a stereo genic centre.

Chirality: The geometric property of molecules where the structure of the molecule and its mirror image are not superimposable is known as chirality. Chiral molecules are optically active and they can rotate the plane polarized light.

R and S nomenclature: it is used to assign the molecule using CIP (Cahn-Ingold-Prelog) rules.

The CIP rules are as follows:

Select the chiral carbon and assign the numbers according to the decreasing atomic mass of atoms attached to it.

If the numbering follows clockwise direction then the molecule is termed as R and if it follows anti-clockwise direction then molecule is termed as S.
