Verma, V. N.; Rai, D. K. published an article in 1971, the title of the article was Electronic absorption spectrum of 2-fluoro-4-chlorotoluene in the vapor phase.Formula: C7H6ClF And the article contains the following content:
The electronic absorption spectrum of 2-fluoro-4-chlorotoluene vapor has been studied in the near-uv region and the assignments for the observed bands have been made assuming Cs symmetry for the mol. The strongest band at 36,517 cm-1 has been assigned as the (0,0) band and the bands have been analyzed in terms of 3 ground-state (150, 217, and 253 cm-1) and 9 excited-state (347, 491, 560, 711, 768, 933, 1012, 1054, and 1199 cm-1) frequencies. The experimental process involved the reaction of 4-Chloro-2-fluorotoluene(cas: 452-75-5).Formula: C7H6ClF
4-Chloro-2-fluorotoluene(cas:452-75-5) belongs to chlorides. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst. Formula: C7H6ClF
