For example, n-propylbenzene is oxidized to propiophenone, benzyl methyl ketone, and several chlorinated products, with benzyl methyl ketone being the major product.
This passage describes the reaction of n-propylbenzene with an oxidizing agent, leading to the production of various products, including propiophenone, benzyl methyl ketone, and chlorinated derivatives.  Benzyl methyl ketone is the most abundant product formed.
