3) On the lab manual, you are asked to set aside a little bit of the reaction crude (The crude is the mixture at the end of every reaction). After recrystallization of the rest of the crude, you are asked to take the melting point of the crude and compare it to the melting point of the recrystallized product. The melting point of the pure product is expected to me between 178-180 °C. How would you expect the melting point of the crude to differ from that of the recrystallized product?
