Web9 mrt. 2014 · Lastly, note that meso compounds, due to their racemization, do not rotate "plane polarized light" (ie they are "optically inactive" ).The R stereocenter will rotate light a certain amount in one direction, but the S stereocenter will rotate it the same amount in the opposite direction. Hope this helps! Click to expand... WebEnantiomers and diastereomers are the only two stereochemical relationships that you can have between any two molecules. The stereoisomers are any two molecules that fulfill the following two requirements: Both molecules must have the same molecular formula, and Both molecules must have the same atom connectivity. So, what’s the difference then?
