Green Chemistry and Atom Economy: Why Percentage Yield Is Not Enough
Environmental Chemistry · Class 11–12 Green Chemistry and Atom Economy: Why Percentage Yield Is Not Enough A reaction can give a 95 per cent yield and still waste most of the mass it started with. Atom economy is the number that shows it. Class 11 & 12 · Environmental Chemistry · Concept The short answer: Percentage yield asks how much of the theoretical product you actually obtained. Atom economy asks a different question — what fraction of the mass of the reactants ends up in the product at all, even in a perfect reaction. A substitution or elimination discards atoms…
