2‐phenylcyclohexanone is 0.25 mmol, therefore the NMR yield is 0.0154 mmol/0.25 mmol = 6%. NB: in this case, the amount of internal standard has been chosen so that the integral of the product peak gives the NMR yield directly when the integral of the internal standard is normalised to 1.00.

Theoretical Yield • The theoretical yield is the amount of product that can be made – In other words itʼs the amount of product possible from stoichiometry. The “perfect reaction.” • This is different from the actual yield, the amount one actually produces and measures

Organic Chemistry Friedel-Crafts Alkylation of Dimethoxybenzene: Description & Background 0.027 mol salicylic acid X 138.12 g = 3.72g mol 3. Divide the number of grams of product obtained experimentally, by the number of grams obtained in the theoretical yield calculations and multiply by 100 to calculate the percent yield.

Organic Chemistry Calculations There are three basic units for measurement in the organic laboratory – mass, volume, and number, measured in moles. Most of the other types of measurements are combinations of them, including density, molecular weight, molarity, and percent composition. Percent yield and percent
