Calculating the Percentage Atom Economy of a Reaction

WebbATOM ECONOMY: The traditional way of evaluating the efficiency of an organic reaction is to determine the percent yield of the reaction. Most organic chemists would be quite pleased with a reaction with >90% isolated yield of the target molecule. On the other hand, a yield of 30% is typically considered to be a disappointment.
