What's the difference between nitrobenzene and nitrobenzol?
Nitrobenzene
Definition:
(n.) A yellow aromatic liquid (C6H5.NO2), produced by the action of nitric acid on benzene, and called from its odor imitation oil of bitter almonds, or essence of mirbane. It is used in perfumery, and is manufactured in large quantities in the preparation of aniline. Fornerly called also nitrobenzol.

(15) To define these features more precisely, we examined the inductive potencies (by measuring quinone reductase in murine hepatoma cells) of two types of glutathione transferase substrates: a series of 1-chloro-2-nitrobenzenes bearing para-oriented electron-donating or -withdrawing substituents and a wide variety of other commonly used and structurally unrelated glutathione transferase substrates.
