Frequently Asked Questions
What is percent yield?
Percent yield is the ratio of the actual product obtained to the theoretical maximum product possible, expressed as a percentage. It measures the efficiency of a chemical reaction.
Why is percent yield usually less than 100?
Percent yield is typically less than 100 due to incomplete reactions, side reactions, loss of product during purification, and measurement errors. Yields above 100 percent indicate impurities.
