Introduction to Stereochemistry

Question	Answer
Stereochemistry	study of of the spatial (3D) arrangements of atoms in a molecule and how the shape of a molecule affects its chemical reactivity.
Molecular geometry around carbon atom	Molecular geometry of carbon is determined by the bonding state. Image: ff916cc4-6319-46d3-a54c-646f0bf9eede.PNG (image/PNG)
