Percent Yield vs Actual Yield
Fórmula
Percent Yield
Percent yield measures how efficient a chemical reaction is by comparing the actual product obtained to the maximum amount theoretically possible.
Formula
% Yield = (Actual Yield / Theoretical Yield) × 100
Theoretical yield is calculated from stoichiometry using the limiting reagent. Percent yields below 100% are caused by incomplete reactions, side reactions, and losses during purification.
Ejemplo Resuelto
A synthesis produces 3.5 g of product from a theoretical maximum of 5.0 g.
- 01% Yield = (3.5 / 5.0) × 100 = 70.00%
- 02Product lost = 5.0 - 3.5 = 1.5 g
Preguntas Frecuentes
Can percent yield exceed 100%?
In theory, no. A yield above 100% usually means the product is impure (contains solvent, byproducts, or unreacted starting material) or there is a measurement error.
What is a good percent yield?
It depends on the reaction. Simple reactions may give 90%+ yield. Multi-step organic syntheses often give 50-80% per step. Transition metal-catalyzed reactions can vary widely from 30-95%.
How do I find the theoretical yield?
Identify the limiting reagent using stoichiometry, then calculate the maximum moles of product from the limiting reagent. Multiply by the product molecular weight to get grams.
