In green chemistry, atom economy is an important concept used to measure how efficiently atoms of the reactants are incorporated into the desired product. In a substitution reaction, atom economy is generally less than 100% because a part of the reactant is eliminated as a by-product and does not become part of the main product. This leads to waste generation, which is undesirable from an environmental perspective. A suitable example of a substitution reaction is the preparation of bromoethane from ethanol using hydrobromic acid. In this reaction, ethanol reacts
