NH, CI- Pararosaniline is a colourless fluid (if pure), paratoluidine a colourless, crys- talline solid. Heat them in the presence of a mild oxidizing agent and a source of chloride ions, and a brilliant colour develops. Two molecules of aniline combine with one of para- toluidine to give a substance in which one of the three rings is quinonoid. To which of the three rings is colour due: to those derived from aniline, or to that derived from paratoluidine ? The formula ci-. NH2 Pa
