  • * This reaction is catalyzed by Lewis acids like anhydrous AlCl 3, FeX 3, ZnCl 2, BF 3 etc. * It is a reversible reaction and hence dealkylation is also possible under the above said conditions. * The Friedel-Crafts alkylation fails when the aromatic systems contain more powerful electron withdrawing groups than halogens (like nitro group).
  • Stoichiometry is the calculation of quantities in chemical reactions. Equations tell chemists what amounts of reactants to mix and what amounts of products to expect. You can determine the quantities of reactants and products in a reaction from the balanced equation.
  • Feb 20, 2012 · We use percent yield to calculate the amount of products obtained in an equation. Formula: Percent yield = grams of actual product recovered x 100 % grams of product expected from stoichiometry Example: 2 C3H8 + 7 O2 --> 6 CO + 8 H2O If 100.0 g of C3H8 is reacted with excess O2 and 50.0 g of CO was produced, what is the percent yield ?

Using stoichiometry, students can predict the amount of product they produce and then compare that prediction to their actual yield. It aligns to the NGSS Practice of the Scientist of Planning and carrying out investigations —students must plan an investigation into how closely theoretical yield and actual yield align. Theoretical yield is rarely ever attained through the actual chemical reaction. Actual yield is the amount of product one actually obtains during the reaction. The ratio of the actual yield to the theoretical yield, multiplied by 100 percent, gives the percent yield: Equation 4.6. MCAT EXPERTISE
