This is a set of practice problems to help master the concept of limiting reactant which is critical in calculating the amount of product that can be obtained in a chemical reaction. Remember, if the reactants are not in stoichiometric ratio, one of them is the limiting reactant (LR), and the other is in excess. Doing practice problems is the only way to master organic chemistry! At Chemistry Steps, you can find all the topics of Organic 1 and 2 and their associated practice problems. There are more than 1000 practice questions and you can find them after each article listed below. Here are some examples from the topics shown below. 3.
