tion:The addition of hydrogen HALIDE to an unsymmetrical alkene gives TWO PRODUCTS. Propene on reaction with hydrogen BROMIDE forms 80 % 2- bromopropane (isopropyl bromide) and 20% 1-bromopropane(n-propyl bromide)The addition of hydrogen halide to an unsymmetrical alkene gives two products. Propene on reaction with hydrogen bromide forms 80 % 2- bromopropane (isopropyl bromide) and 20% 1-bromopropane(n-propyl bromide)Propene when REACTED with HBr in presence of peroxide, it gives 1,-Bromopropane. The addition is according to Anti Markovnikovs rule.The addition of hydrogen halide to an unsymmetrical alkene gives two products.

The hydrogen of HBr adds to Carbon 1 of propene and bromine adds to Carbon 2have a good daygood life on
