5. When the solid in the capillary tube starts to melt, observe the melting point temperature. When the solid completely melts, observe the temperature. The two temperatures are called the melting point range.
6. Do the melting points of the following organic compounds:
Acetanilide
Benzamide
Naphthalene
p-dichlorobenzene
urea
7. Compare the experimental melting points with the theoretical melting points (found in reference books and indicate your references on your report.)
