OH
H+
Y
Note: You may assume you have an excess of either reactant if the reaction requires more than one of those molecules to form the
products.
In the drawing area below, draw the skeletal ("line") structures of the missing organic products X and Y. You may draw the
structures in any arrangement that you like, so long as they aren't touching.
