Photohalogenation
WebExpert Answer. Consider the photohalogenation of 2,3-dimethylbutane using C2 (g). Draw the possible monohalogenated products. Given that 3° hydrogens are 5.2 times more reactive than 1° hydrogens toard abstraction by chlorine radicals, calculate the expected ratio of 3 monochlorinated product to 1° monochlorinated product formed CH3 Cl-CH2 ... In chemistry, halogenation is a chemical reaction that entails the introduction of one or more halogens into a compound. Halide-containing compounds are pervasive, making this type of transformation important, e.g. in the production of polymers, drugs. This kind of conversion is in fact so common that a comprehensive overview is challenging. This article mainly deals with halogenation using elemental halogens (F2, Cl2, Br2, I2). Halides are also commonly introduced …
