B. Draw the major product for each of the following reactions or reaction sequences. You needn t bother to show side products or minor products. For chiral molecules that are racemic, you needn t draw both enantiomers. BE CAREFUL TO SHOW THE CORRECT ORIENTATION, AND THE CORRECT STEREOCHEMISTRY IN CASES WHERE STEREOCHEM IS FACTOR.
