Green Chemistry Vocabulary

Atom Economy –
1) The mass of desired product divided by the total mass of all reagents, times 100

Mass of Desired Product
Total Mass of all Reagents

Percent Atom Economy = x 100
2) The mass of desired product divided by the total mass of all products and
byproducts produced, times 100
3) A measure of the efficiency of a reaction

Green Chemistry
1) Designing chemical products and processes to reduce or eliminate the use or
generation of hazardous materials
2) Using chemistry for pollution prevention
3) Benign by design, sustainable chemistry

Molecular Weight – mass of one mole of a compound (units of grams per mole)

Percent Yield – actual yield divided by theoretical yield times 100

Theoretical Yield – the maximum amount of product that can be produced from the
quantities of reactants used; the amount of a given product formed when the
limiting reactant is completely consumed

Saponification – the decomposition of triglycerides with aqueous sodium hydroxide

Stoichiometry – application of the laws of definite proportions and conservation of mass to chemical processes; quantitative relationship between compounds involved in
a reaction
