136 No. V. On the action of Ozone on Carbon lI'Ionu;dde~' by IRA REMSEN and MASE S. SOUTHWORTH. One of the most remarkable examples of so-called nonsaturated compounds is carbon monoxide. If we accept the hypothesis of constant valence, the compound CO must possess free affinities, or, as some chemists believe, the two affinities of the carbon-atom, which are not saturated by the ox,ygen atom, must exercise an influence upon each other. We can not explain this case by assuming that two
... g that two carbon-atoms are joined together by two affinities each, for we know that the formula of carbon monoxide is CO, and not C 2 0 2 or a higher multiple, and, accepting tbis formula, it is plain that we cannot assume a double union of carbon atoms in the compound. If, on the other hand, we accept the hypothesis of variable valence, believing that the valence of an element depends upon circumstances, we shall look in vain for circumstances which, in the one case, can cause the bivalence, in the other the quadrivalence, of the carbon-atom. A difference ill temperature certainly does not cause the difference in valence. 'file atom * Annalen der Chemie, Suppl. VII, 218. Ozone on Carbon .Monox~·de.
