What is the value of percent atom economy when an organic compound of formula weight 75 u is obtained from reactants having sum formula weight 225 u ?

Options

  1. A13.5
  2. B33.3
  3. C40.4
  4. D70.5

Correct answer

B. 33.3

Step-by-step solution

% atom economy = Formula weight of the desired product Sum of formula weight of all the reactants 100 used in the reaction % atom economy = 75 225 100=33.3
