The addition of hydrogen bromide to 1,3-butadiene at two different temperatures give two products in different amounts as given below. array lll 1,3-butadiene + HBr 1,3-butadiene + HBr & -80 ^ C & 1-bromo-2-butene ( p %)+ 3-bromo-1-butene ( q %) array In these reactions, the first step is the addition of proton to one of the double bonds to form carbocation. At a lower temperature, the more stable carbocation is imme
