Addition of HBr to PROPENE forms 2- Bromopropane but in the presence of benzoyl peroxide 1- Bromo propane is formed due to Per oxide effect / anti markonikov's effect / kharsh effect.
 
According to the peroxide effect, the negative part of the addinum (Br -)goes to that carbon atom which has higher number of hydrogen atoms bonded to it.
 
b) Ozonolysis of Propene yields a mixture of Methanal and Ethanal.
