WebJan 30, 2016 · In order for optical isomerism to occur a chiral carbon has to be present. This is a carbon that is bonded to four different groups within the molecule. In the case of thalidomide there is only one chiral carbon in the molecule so only two possible isomers can occur. However one of these isomers causes the birth defects that are unwanted and ...
