In this instance, the observed ortho/para ratio is almost 2:1, as we might expect. However, if we study the ortho/para ratio found in the nitration of a number of other arenes, we see that this is not always the case.

WebJournal of the Chemical Society (Resumed) X.—Chlorination of o - and p - nitrotoluenes. 3 : 4 : 6-Trichloro-2-nitrotoluene and 2 : 6-dichloro-4-nitrotoluene Leopold Ferdinand Levy and Henry Stephen Abstract The first page of this article is displayed as the abstract.
WebAlso, as noted earlier, toluene undergoes nitration about 25 times faster than benzene, but chlorination of toluene is over 500 times faster than that of benzene. From this we may conclude that the nitration reagent is more reactive and less selective than the halogenation reagents. Both sulfonation and nitration yield water as a by-product.
