A graduate student doing research had the following TLC plate. Lane one is starting material, lane two is thedesired product and lane three is the reaction mixture that the student isolated. (a) Did the reaction go tocompletion? Explain briefly. (b) Was the desired product formed as desired? Explain. (c) Did the reactionproduce one pure compound? Explain briefly. (10 pts)1 2 3HCH 3H(a) The reaction did NOT go to completion because there is still a spot in the product(lane 3) that corresponds to the starting material.(b) The desired product was formed, since there is a spot in lane 3 that correspondsto the desired product in lane 2.(c) The product was not pure. Besides the remaining starting material, there was oneother compound produced, an impurity.2
