The best sequence of reagents is given in option C. The conversion of o-xylene to o-diaminobenzene involves multiple steps and option C provides the required steps in the correct sequence. The initial step involves the oxidation of o-xylene to o-phenylenediacetic acid using KMnO4 and heat. This is followed by the decarboxylation of o-phenylenediacetic acid to 1,2-diphenylethylene using H2SO4. The next step involves the conversion of 1,2-diphenylethylene to o-phenylenediamine using PCl5 and then to o-diaminobenzene using NHS and Br2/OH-. This sequence of reagents provides a reasonably efficient and reliable method for the conversion of o-xylene to o-diaminobenzene.
