- Propene reacts with hydrogen bromide (HBr) at room temperature to produce, 1-bromopropane and 2-bromopropane. H2C=CHCH3 + HBr → CH2(Br)CH2CH3 + CH3CH(Br)CH3 Draw out the reaction mechanism of the reaction between propene and hydrogen bromide to produce 2-bromopropane. Use curly arrows to show the movement of electrons. The description should be detailed and must include the type of bond fission that takes place. You may sketch and insert suitable diagrams to aid your description if you wish. Referring to the above mechanism, explain why two products are formed in the reaction between propene and hydrogen bromide?arrow_forward12.Use of KMnO, to effect oxidative cleave of the alkene J, C3H16, yields two fragments, one of which is butanoic acid and the other a ketone, Q.
