Halogenation of Methane - Online Organic Chemistry Tutor

WebThe halogenation regiochemistry of alkanes is generally determined by the relative weakness of the available C – H bonds. For the industrial processing of chlorinated methane, free radical halogenation is used: CH 4 + Cl 2 → CH 3 Cl + HCl. These free radical reactions also go with rearrangement. WebMethane does not react with iodine, on the other hand. Because two molecules of gaseous products are generated from two compounds of gaseous starting products, the reaction entropy of methane halogenation is close to zero. As a result, the reaction enthalpy (H°) determines the thermodynamics of methane halogenation first and foremost.
