The configuration to each of the given compounds is to be assigned. Concept introduction: The molecules that are non-superimposable or not identical with its mirror image are known as chiral molecules. A pair of two mirror images that are non-identical is known as enantiomers. The enantiomers in which the path traced from the highest atomic number to the lowest atomic number is in anticlockwise direction are designated as S provided that among the four groups attached to the chiral carbon, the least priority group is in horizontal position in Fischer projection. The enantiomers in which the path traced from the highest atomic number to the lowest atomic number is in the clockwise direction are designated as R provided that among the four groups attached to the chiral carbon, the least priority group is in horizontal position in Fischer projection. The objects or molecules which are superimposable with their mirror images are achiral objects or molecules, and these objects have a centre of symmetry or plane of symmetry.

Interpretation Introduction

Interpretation:

The configuration to each of the given compounds is to be assigned.

Concept introduction:

The molecules that are non-superimposable or not identical with its mirror image are known as chiral molecules.

A pair of two mirror images that are non-identical is known as enantiomers.

The enantiomers in which the path traced from the highest atomic number to the lowest atomic number is in anticlockwise direction are designated as S provided that among the four groups attached to the chiral carbon, the least priority group is in horizontal position in Fischer projection.

The enantiomers in which the path traced from the highest atomic number to the lowest atomic number is in the clockwise direction are designated as R provided that among the four groups attached to the chiral carbon, the least priority group is in horizontal position in Fischer projection.
