Which from following formulae is a correct formula to determine percent atom economy?

Options

  1. A% Atom economy = Formula weight of product 100
  2. B% Atom economy = Sum of formula weight of all reactant 100
  3. C% Atom economy = Formula weight of desired product Sum of formula weight of allreactant 100
  4. D% Atom economy = Sum of formula weight of all reactant Formula weight of desired product 100

Correct answer

C. % Atom economy = Formula weight of desired product Sum of formula weight of allreactant 100

Step-by-step solution

Atom economy is the conversion efficiency of a chemical process in terms of all atoms involved and the desired products produced. % Atom economy = Formula weight of desired product Sum of formula weight of allreactant 100
