WebThe major product is predicted by the Markovnikov rule, which states that when a hydrogen halide is added to an asymmetrically substituted alkene, the major product results from the addition of the hydrogen atom to the double‐bonded carbon that is attached to more hydrogen atoms, while the halide ion adds to the other double‐bonded carbon. WebMarkovnikov Rule predicts the regiochemistry of HX addition to unsymmetrically substituted alkenes. The halide component of HX bonds preferentially at the more highly substituted …
