The reaction yield (absolute yield) of a chemical reaction is the amount of pure and dry product yielded in a reaction Normally, in order to measure the efficiency of a chemical reaction in organic synthesis, the relative or percentage yield (%) is calculated Before calculating the yield of a reaction (necessary when preparing the laboratory notebook) it is crucial to know the stoichiometryTheoretical yield formula Using the theoretical yield equation helps you in finding the theoretical yield from the mole of the limiting reagent, assuming 100% efficiency So, to stop you from wondering how to find theoretical yield, here is the theoretical yield formula mass of product = molecular weight of product * (moles of limiting reagent in reaction * stoichiometry of product)All chemical reactions have two yields First, is the actual yield and second, is the theoretical yield To compute for the actual yield, you must also have the theoretical yield so that you can determine the efficiency of the reaction As for the theoretical yield, this is the value for a reaction that's 100% efficient
Key Difference – Percent Yield vs Percent Recovery Percent yield is the amount of a compound obtained from a chemical synthesis reaction with respect to the theoretically expected amount This is a percentage value It is used to determine the efficiency of a chemical reaction percent recovery is a term that is often used in organic chemistry regarding recrystallization processesIn chemistry, theoretical yield is a term that describes the amount of product that would result from a chemical reaction, assuming that chemical reaction completesA chemical reaction is only considered complete when the entire limiting reactant is used up and it is impossible to create more products from the remaining chemicalsReactants often yield quantities of products that are less than those calculated based on the formulated chemical reaction The per cent yield formula is used to determine the percentage of the theoretical yield that was formed in a reaction
Each product has a theoretical yield, meaning the amount of product you would expect to get if the reaction is perfectly efficient Continuing the example above, you are analyzing the reaction 6 O 2 C 6 H 12 O 6 {\displaystyle 6O_ {2}C_ {6}H_ {12}O_ {6}} → 6 C O 2 6 H 2 O {\displaystyle 6CO_ {2}6H_ {2}O}Yield variance is the difference between actual output and standard output of a production or manufacturing process, based on standard inputs of materials and laborThe formula for percent yield is Example The medical drug aspirin is made from salicylic acid 1 mole of salicylic acid gives 1 mole of aspirin Given that the chemical formula for salicylic acid is C 7 H 6 O 3 and the chemical formula for aspirin is C 9 H 8 O 4
