You should find two meso structures and one pair of enantiomers. (b) Star (*) the asymmetric carbon atoms, and label each as (R) or (5). (c) in the meso structures, show how C3 is not asymmetric, nor is it a chiral center, yet it is a stereocenter. (d) In the enantiomers, show how C3 is not a stereocenter.
