Would you expect the reactivity of a five-membered ring ether such as tetrahydrofuran (Table 10.2) to be more similar to the reactivity of an epoxide or to the reactivity of a noncyclic ether? Why?

In the presence of 18-crown-6, potassium permanganate dissolves in benzene to give "purple benzene," a useful reagent for oxidizing alkenes in an aprotic environment. Use a drawing of the complex to show why KMnO₄ dissolves in benzene and why the reactivity of the permanganate ion is enhanced.

(A true story.) An inexperienced graduate student moved into a laboratory and began work. He needed some diethyl ether for a reaction, so he opened an old, rusty 1-gallon can marked 'ethyl ether' and found there was half a gallon left. To purify the ether, the student set up a distillation apparatus, started a careful distillation, and went to the stockroom for the other reagents he needed. While he was at the stockroom, the student heard a muffled "boom." He quickly returned to his lab to find a worker from another laboratory putting out a fire. Most of the distillation apparatus was embedded in the ceiling.
