3. Optical Isomers.
28 February 2019
The 3-D formulae show the spatial arrangements of the atoms. If these two isomers are placed on top of each other they do not mach, they are non-superimposable.

4. Optical Isomers
28 February 2019
For a compound to be optically active it must have a chiral centre. A chiral centre (or carbon) is a carbon atom in a molecule that has four different groups. Chiral molecules are non-superimposable on their mirror image.
