please help and explain

Build two models of chlorocyclohexane. On one model, replace the hydrogen labeled Ha with a chlorine atom to make model A; on the other model, replace the hydrogen labeled Hb to produce model B. Now place both models in the chair conformation. Assign absolute stereochemistry to all stereogenic centers in the pictures of models A and B be What is the configuration of each chirality center? A2 ? B? (R)S C?R(S)D?(R)S What is the stereochemical relationship between models A and B ? (Circle your answer) identical (enantiomers diastereomers meso inzinn 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? Would a solution of model A rotate plane polarized light? Model B? If both models do, what is the relationship between this rotation
