The first stage is formation of hydrogen bromide (HBr), a gas, and some of the HBr is further oxidized by the sulfuric acid to form bromine (Br 2 ) and sulfur dioxide (SO 2 ). Source: Internet
This is usually done using "chemical intuition": in the above example, hydrogen bromide dissolves in water to form H + and Br − ions, so it may be assumed that bromine is more electronegative than hydrogen. Source: Internet
Why hydrogen bromide exhibited both Markovnikov as well as reversed-order, or anti-Markovnikov, addition, however, was not understood until Morris S. Kharasch offered an explanation in 1933. Source: Internet
