    Green synthesis of Chalcones: we carried out a reaction of green synthesis of chalcones using 4-methylacetophenone and 4-methylbenzaldehyde. Ideally we should have used 5 mmol for each, but we used 0.6 ml of 4-methylacetophenone and 0.5ml of 4-methylbenzaldehyde. Draw the complete reaction of this experiment, and show what is the limiting reagent that should be used to calculate percent yield.
