Concept explainers
(a)
Interpretation:
The number and kind of stereoisomers formed when given molecule is treated in presence of
Concept Introduction:
Geometric isomers: Two atoms with the same side location of the double bond are called cis isomers and two atoms with opposite side locations of the double bond are called Trans isomers.
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
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.
