1. Stereoisomers 9/16/2025 1 Dr Seemal Jelani Chem-261

2. All molecules have a mirror image – but for most molecules it is the same molecule. 9/16/2025 2 Dr Seemal Jelani Chem-261

3. For some molecules the mirror image is a different molecule (the mirror image is non-superimposable). 9/16/2025 3 Dr Seemal Jelani Chem-261

5. Left and right hands are an example of non-superimposable mirror images. 9/16/2025 5 Dr Seemal Jelani Chem-261

6. This usually happens when a molecule contains a C atom with four different groups attached ( chiral / asymmetric C ). Such molecules are said to be chiral or optically active . 9/16/2025 6 Dr Seemal Jelani Chem-261
