p-toluic acid is prepared from 3.42 grams of p-Bromotoluene. When p-Bromotoluene was mixed with dry ether, the mixture was warmed until the ether begins to boil (34.6 °C).  When the reaction is almost complete, dry ice (3-4 mL in a beaker) was prepared and the mixture was poured into it. After some time, 5 mL of 6 N HCl was added. The solvent used for the recrystallization is 100 mL of 30% ethanol. The reaction equation is given on the figure. What is the actual yield? What is the theoretical yield? How many moles of p-toluic acid was produced?
