Question

What is the difference between a stereogenic center and a chiral center?

Answer 1

The differences between a stereogenic center and a chiral center are discussed below:

Stereogenic center	Chiral center
A stereocenter is a point in a moelcule that gives rise to stereoisomers molecule	A chiral center is a carbon atom in which four different groups of atoms are present.
The carbon in the stereocenter is ${\mathrm{sp}}^2$ or ${\mathrm{sp}}^3$ hybridized.	A chiral center is ${\mathrm{sp}}^3$ hybridized.
It can have either three or four groups of atoms.	It essentially has four groups of atoms.
Stereocenters can have either single or double bonds.	Chiral centers have only single bonds around them.
For example in trans-2-butene, both 2 and 3 carbon atoms are stereogenic centers.	For example, the molecule given below has a chiral center.
