Question

2. in step 21, explain why hydrochloric acid cannot be used in place of sulfuric acid ? Slowly add about 1.5 mL of ice-cold 3 M sulfuric acid dropwise to the reaction mixture. Add slowly to avoid frothing of the reaction mixture. The contents of the vial may solidify. Use a small glass stirring rod or spatula to break up the solid during the acidification. If needed, close the vial and shake with venting to induce dissolution of all solid materials. Two distinct layers should appear when all the material is in solution. 3. if there was another spot on the TLC plate what would be that other spot assuming all starting materials was consumed? at what stage of the workup do we separate this byproduct from triphenylmethanol?
