Question

Which is greener:

A) a reaction with 90% yield and 15% atom economy

Or

B) a reaction with 60% yield and 80% atom economy.

EXPLAIN YOUR ANSWER

Answer 1

more atom economy reaction will be more greener

so answer is B) a reaction with 60% yield and 80% atom economy.

explanation:

for any reaction yield is most important factor . but along with good yield we need to look at wasteage of by-proudcts and the reaction should be minimize the mass lost of reactants or products.

for first reaction 90% yield but atom economy is 15% it is indicates there is more loss of reactants and by-products

there not eco-friendly . so this reaction is not treated as greener

but 80% atom economy reaction will be greener because in this case loss of material lesser
