Frequently Asked Questions
What is Stereochemistry?
Stereochemistry is a subtopic in Organic Chemistry. It is the study of the different spatial arrangements of atoms in molecules. It includes 3 dimensional structure of molecules and their proper effect on physical and chemical properties.
What is S and R in Stereochemistry?
In Stereochemistry, S and R denote the absolute configuration of a chiral centre. S stands for sinister (Latin for left) and R stands for rectus (Latin for right).
Is Z and E Stereochemistry?
E-Z configuration or E-Z convention is the IUPAC preferred method of describing the absolute stereochemistry of double bonds in organic chemistry.
Why is Stereochemistry important?
Stereochemistry is of critical importance to drug action as the shape of a drug molecule is an important factor in determining its interaction with the various biological molecules like enzymes and receptors that it faces in the body.
Who is the father of Stereochemistry?
Jacobus Henricus van’t Hoff is considered as the father of Stereochemistry. He was a physical chemist, he theorized advanced convincing evidence that the performance of gases, as illustrated by Boyle’s Law, could be applied equally to solutions.
