How to convert propane 2 ol to 1 bromopropane,with reaction

Answer 1

We need the anti-markovnikov product here as a result of the subsitution. So, we make use of the Karasch effect, that is HBr/H2O2, in presence of peroxide, the reaction gives anti markovnokov as the reaction undergoes radical mechanism.
So, CH3-CH(OH)-CH3 + Br2/H2O2 -> CH3-CH2-CH2Br
