Although nmr has been routinely used to determine/estimate relative number of protons for structure elucidation, it has been rarely used to determine and report the purity of organic compounds. In this video, we are going to learn how to calculate the yield and conversion of a reaction using the quantitative nmr method. Divide your desired product's mass by the total mass to get your purity.multiply by 100 % to get a percentage.
