For a dimerization reaction
WebDimerization reaction. Photodimerization is common for anthracenes, less so for naphthalenes, and until this year only one example of this reaction with a benzenoid compound had appeared. Thus irradiation of [Pg.322] Over the years there have been many reports that photoreactions, particularly dimerization processes, carried out in micelles ... WebChlorine trifluoride is prepared by the reaction Cl 2 ( g) + 3F 2 ( g) 2ClF 3 ( g). Write the equation that relates the rate expressions for this reaction in terms of the disappearance of Cl 2 and F 2 and the formation of ClF 3. 4.
