Interpretation Introduction

Interpretation:

The correct structure of the given compound has to be drawn and its absolute stereochemical configuration should be provided.

Concept introduction:

In a cyclic compound, the spatial orientation of the di substituents cyclic compound must be viewed as a three-dimensional conformation. Generally, a solid wedge bond indicates it is above the plane of the ring and a broken wedge bond indicates it is below the plane.

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

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.
