 543  316. A rough idea of what is thought to be taking place is given by the formula below, the dotted curved arrows indicating the movement of single electrons and not of electron pairs. 317. New polyhydroxyanthraquinones were synthesized and some of them were found applicable as mordant dyes. 318. The diastereoisomers of these substances are designated by the prefixes L-allo and D-allo, the latter denoting the configuration of the a-carbon atom. 319. Bohn also obtained theblue dye and recognized the substance as having a condensed-ring system. 320. Such groups were subdivided depending upon whether the longer or shorter chain occupies the 2-position. 321. At least three hexadecenoic acids have been stated to occur in the natural oils, which raises the question to as whether they are structurally identical or are different acids. 322. The centrifugation was continued with distilled water for the same number of times as before, the last centrifugation yielding in nearly all cases a dilute colloidal solution of the polymer. 323. Taking these forms for simplicity as being individuals rather than the canonical extremes of a mesomeric hydrid we get. 324. It is difficult to assess these effects numerically, but advocates of this interpretation consider that, with all the adverse influence acting jointly, an inefficiency factor of about 107 could be understood to be present. 325. For the sake of clarity the reactions have been separated as steps, but actually are to be pictured as taking place almost simultaneously by a circulation of electrons, the intermediate stages never actually becoming free as individual molecular species. 326. Although this state of NO has been predicted by Mulli-ken to be a bound state, it is considered separately because insufficient spectroscopic data are available. 327. We expect the delegation to arrive in a few days. 543 |
