Optical
Geometric
What is a chiral molecule?
A molecule that can not be superimposed on its mirror image.
What is the name of a molecules that is not chiral?
Achiral
What is a chiral centre?
An atom that has 4 different groups attached to it
What does asymmetric mean in reference to a carbon atom?
A carbon atom in a molecule that is joined to four different atoms or groups.
What are enantiomers?
Isomers that are related as object and mirror image.
Are achiral molecules superimposible?
Yes
What does it mean if a molceule has a chiral centre in terms of isomerism?
It can exist as an optical isomer
Similarities and differences in the properties of optical isomers.
same chemical properties
Similar physical properties
Different biological properties.
