You and your lab mate have just finished extracting trans-lycopene from tomatoes. Your lab partner thinks it would be fun to add elemental bromine to the trans-lycopene that has been dissolved in hexane and see what happens. As exciting as it sounds, the solution simply decolored immediately. If the solution had 100mg of trans-lycopene in it, how many moles of elemental bromine would be required to completely react at all possible reaction sites? How many total stereocenters are formed? How many different products are there?
