Theoretical yield of benzoin

The benzoin addition is an addition reaction involving two aldehydes. The reaction generally occurs between aromatic aldehydes or glyoxals, and results in formation of an acyloin. In the classic example, benzaldehyde is converted to benzoin. The benzoin condensation was first reported in 1832 by Justus von Liebig and F… WebbPrior to beginning the experiment, the theoretical yield of benzil was discovered. The limiting reactant in the reaction, benzoin + nitric acid benzil, was benzoin at 0.00141 moles. This value was discovered by the initial amount of the reactants used: 0.30 grams benzoin and 1.5 ml Nitric Acid (see Eq 1).
