5

What is stereoisomerism?

This is where two molecules are identical in contents and bonding, however the arrangement in space differs. That is too say that the molecules are no longer super-imposable. They can either be enantiomers or diastereomers.

6

What is the difference between enantiomers and diastereomers?

A enantiomers is the mirror image of a molecule, however is not superimposable.
A diastereomer is any other arrangment that is still not superimposable.
