C357 Practice Problem Set #8 /Stereochemistry Page 1 of 2 1) For each of the following compounds, decide which carbon atoms are stereocenters and then assign the absolute configuration (R,S) of each. 2) Describe how d and l configurations are determined for individual molecules. 3) Does the d,l system have any relationship to the R,S system? If so, is a d molecule R or S? 4) Define an enantiomer. 5) What is a chiral compound? 6) Define Meso. 7) Do all compounds rotate plane-polarized light? If so, why do pure chiral compounds show a net rotation of the light?
