Concept explainers
(a)
Interpretation:
(R)-2-chlorobutane or (S)-2-chlorobutaneto has to be identified from the given compound.
Concept introduction:
R and S nomenclature: it is used to assign the molecule using CIP 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.
(b)
Interpretation:
(R)-2-chlorobutane or (S)-2-chlorobutaneto has to be identified from the given compound.
Concept introduction:
R and S nomenclature: it is used to assign the molecule using CIP 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.
