Reactivity trend of silver halides
WebDec 1, 2024 · The mechanism of this reaction was investigated by DFT and we found a viable pathway that also explains the trend and magnitude of enantioselectivity through the halide series in good agreement with the experimental data. The in-depth investigation of substrate con-formers during the reaction turned out to be crucial in obtaining an … WebAlkyl Halide Reactions. The functional group of alkyl halides is a carbon-halogen bond, the common halogens being fluorine, chlorine, bromine and iodine. With the exception of iodine, these halogens have electronegativities significantly greater than carbon. Consequently, this functional group is polarized so that the carbon is electrophilic ...

WebThis establishes the trend in reactivity of the halogens down Group 17, which could be extended by investigating the reaction of bromine water with halide ions in solution. The reactivity is related to the oxidising power of the halogens, which decreases down the group. Silver halides are used in photographic film and photographic paper, including graphic art film and paper, where silver halide crystals in gelatin are coated on to a film base, glass or paper substrate. The gelatin is a vital part of the emulsion as the protective colloid of appropriate physical and chemical properties. The gelatin may also contain trace elements (such as sulfur) which increase the lig…
