WebAug 2, 2024 · This reaction is called free-radical chlorination and the mechanism involves 3 main steps. The first step is called the chain initiating step where the chlorine molecule splits into 2 chlorine radicals. The splitting of the chlorine molecule into the 2 radicals requires UV light as this supplies the energy needed to break the covalent bond between the 2 … WebUV-spectrophotometry determination with taurine it’s UV spectra cover those of taurine in analytical zone from 190 to 400 nm (fig. 2, (1)). Due to this authors take advantage to the fact that taurine reacts selectively with ninhydrin after warming. The product of reaction is a color compound and it
