Each of the following compounds, AC, is equally soluble in the three solvents listed. In each
  case, which solvent would you choose? Give reasons for your answer. (More than one answer
  may be correct.)
  (a) Compound A: benzene, acetone, or chloroform
  (b) Compound B: chloroform, methylene chloride, or ethyl acetate
  (c) Compound C: methanol, ethanol, or water

Question 2

At the end of a reaction, your glassware is covered with a tarry substance. If you use acetone to
  clean the tar from the glassware, can you place the glassware immediately in a drying oven?
  Why or why not?

Answer to Question 1

(a) Acetone is the solvent of choice because it has the lowest boiling pint and is the least toxic
of the three.
(b) Ethyl acetate is the solvent of choice because it is less toxic than chloroform or methylene
chloride. Ethyl acetate is sufficiently volatile that it can be removed easily from the sample.
(c) Any of these would be a reasonable choice, but ethanol would probably be the best. It is
less toxic than methanol. Although ethanol is flammable, it is more vlatile than water and
would be removed easily from the crystals.

Answer to Question 2

Glassware freshly rinsed with acetone must not be put in a drying oven because the acetone
fumes are flammable.
