2. Simple distillation is quick and inexpensive, however, it is only recommended for separating compounds with a large difference in boiling point. A good rule of thumb is that it is only effective at separating compounds if the difference between their boiling points is 60°C or more. On the other hand, fractional distillation, though more time consuming and expensive, allows us to separate compounds with closer boiling points. A good place to look up boiling points and other physical properties of organic solvents is the American Chemical Society's Division of Organic Chemistry website (https://www.organicdivision.org/orig/organic_solvents.html). Use this site to find and record the boiling points of tetrahydrofuran (THF) and diglyme (diethylene glycol dimethyl ether). What type of distillation would you recommend to separate a mixture of THF and diglyme? Explain. 2.
