Chapter 7 : Stereochemistry |
|
|
Summary
Despite what one may perceive from
a printed page or even the computer screen you are now looking at, most molecules
are not 2D objects, they are 3D as a result of the spatial arrangement of the
atoms, groups and bonds. The interaction of molecules (i.e. reactions)
which occur as the result of collisions between these 3D objects in 3D
space, can therefore also have 3D requirements and characteristics. Stereochemistry
is all about the 3D properties of molecules and reactions and has it's own language
and terms that need to be appreciated.
