CH4 Br, Ligtht Q2. (a) CH3Br + HBr Propose a mechanism for the reaction; indicating initiation, propagation and termination. (b) Account for the percent distribution of the products in the given reaction; CH3-CH2-CH3 + C CH-CH2-CH2C1+ C1+55% CH3-CHCI-CH > Q3. -CH=CH2 When alkene X is treated with HI, two products are formed; the major product is formed when an alkyl shift occurred. (i) Draw the two products formed. (b) Propose a reaction mechanism to account for the two products in (i). CI CH3 HC- -C- X CH3
