1. For each reaction below, identify the mechanism involved, and draw the mechanism for the reaction including intermediates (no transition states required). There may be more than one product, if so, draw them both (watch out for rearrangements), Draw the mechanism below the reaction, and then ill in the products on the right side of the equation. Plesse work this out on another pie paper, then transfer your answer to this sheet.
