H3C CH3 Pd/C X + H2 CH;CHCHCHCH3 ČH3 • You do not have to consider stereochemistry. • In the case of a missing reactant, there may be more than one answer. If so, draw all possible reactants, • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate multiple reactants using the + sign from the drop-down menu.
