2. Consider the reaction of 3-methyl-2-pentene with HBr: HBr Show the mechanism and give the product of the reaction.
4-chloro-2-methyl-2-pentene reacts with acetic acid (solvent), two substitution products are urmea, with the rearranged product predominating as shown in the diagram that follows. When small amounts of acetate ion are added to the reaction mixture, no increase in the rate is observed. Propose a mechanism that accounts for these results. Explain clearly why two products are formed (5 points) Minor Major
ii) Describe analytically the steps to be followed for the coordination polymerization of isotactic poly(4-methyl-1-pentene) using the heterogeneous catalyst TiC14/A1Et3/MgCl2/SiO2 and H2 stream for termination. Học A/CH, CHE 4-methyl-1-pentene
Acid-catalyzed dehydration of 3-methyl-2-pentanol gives three alkenes: 3-methyl-1-pentene, 3-methyl-2-pentene, and 3-methyl- 3-pentane. Draw the structures and mechanisms leading to the formation of 3-methyl-1-pentene & 3-methylenepentane .
