make model A; on the other model, replace the hydrogen labeled Hb to produce model B. Now place both models in the chair conformation. What is the configuration of each chirality center? A? B? C?D? What is the stereochemical relationship between models A and B ? (Circle your answer) identical enantiomers Using the templates provided, draw the planar representation (use wedges and dashes!) and both chair Is one chair conformer lower in energy? If so, circle the appropriate conformation above. Are the two chlorine atoms cis- or trans- to each other? Can both chlorine atoms be axial in any chair conformation? Would a solution of model A rotate plane polarized light? Model B? If both models do, what is the relationship between this rotation
