can someone answer all of these questions please ASAP!

Procedure (do it in the fume hood): Dissolve 1.0 g of triphenylmethanol in 20 ml of warm acetic acid, add 2 mL of 47% hydrobromic acid, heat the mixture for 5 minutes on steam bath, cool it and collect the product under suction, wash it with water and hexanes, allow it to dry, take the weight and calculate the % yield. Take the melting point. Results (30 points): Theoretical yield of Triphenylmethyl Bromide g (5 points) If your actual yield was is 1.1g, what is your % yield? (5 points) Draw the reaction mechanism with proper arrow pushing. (30 points) What would be the competing reaction in the process? (10 points) Draw the mechanism for the competing reaction (20 points) What is the reason for not getting the competing reaction in here? (10 points) Write the mechanism for the free radical bromination of triphenylmethane (10 points) If 6.5 g of triphenylmethanol is converted to triphenymethyl iodide, what will be the theoretical yield of iodide (10 points)
