For a carbon to be a stereogenic centre, it needs to have four different groups attached to it.
- This only applies to sp3 carbon atoms. sp2 and sp carbon atoms are flat (all attached groups lie in one plane), and therefore they cannot be chiral.
- If any two groups attached to the sp3 carbon are the same, the carbon will not be chiral.
