- Chemistry question 1 When HBr reacts with an unsymmetrical alkene, e.g. Me2C=CH2, two products are possible. a) when the reaction is carried out in the presence of a radical initiator, the alternative product ( the anti Markovnikov product) usually predominates. Give the mechanism for this reaction, and hence an explaination of the product distribution. b) give the mechanism for the reaction between CH2=CH2 and O3 and name the products formed.Draw the structures of the two carbocation intermediates that might form during the reaction of propene (above) with HBr.draw the two possible carbocations that can form when this alkene reacts with a strong acid (such as HBr or H3O+). of the two structures you drew, circle the more stable carbocation
