Document Summary

Mead is made from honey so you"d find a waxy substance. Derivative from pine is a way of preserving wines. Kind of an archaic technique but still very useful. We are starting with a liquid but if we make a solid, we can do a melting point determination. Melting point is more about purification, not really identification. x-ray crystallography is what helps us prove the identity of something. You want an easy reaction that gives you a high yield. You want it to be easy to purify. Must choose a derivative that has different melting points for different compounds otherwise we will not be able to tell them apart. week 9 page 1. Benzenes are flat so they stack really well and give more dispersion interaction. If you use water and no crystals form, you have to boil it off.
