Write a mechanism for each of the following reactions. Clearly label the initiation,propagation, and termination steps in each reaction. 1. The light-initiated reaction of cyclohexane with chlorine to give chlorocyclohexane. 2.the reaction between cyclobutane and bromine to give bromocyclohexane. 3. The reaction between bromine and propane. 4.the reaction between bromine and cyclohexane to give bromocyclohexane.
Write the free radical halogenation mechanism of ethane. Initiation, propagation step 1&2 and termination.

Write the reaction mechanism (showing arrows) of the synthesis of polystyrene. 4pts • Include and show arrows in 2 initiation steps with benzoyl peroxide forming the phenyl radical. (this is shown in Figure 9 of the lab- just add all arrows) A propagation step of the styrene (the monomer) and phenyl radical. A second propagation step showing polymer growth by reacting styrene and the radical product...
7. MECHANISM Using electron push arrows, provide a logical, detailed, stepwise mechanism for the following transformation. Be sure to show each step in the mechanism, including initiation, and propagation steps as well as at least one termination step. HBr → Br ROOR
1. What is the mechanism of polymerization of styrene with AIBN? Initiation: Propagation: Termination (Show self-termination only):
Consider the following reaction mechanism: 1) Initiation Br2 → 2 Br• 2) Propagation (here a cycle of two steps) Br• + H2 → HBr + H• H• + Br2 → HBr + Br• 3) Termination 2 Br• → Br2 This reaction is catalyzed by platinum. Wat causes the bromine to split in the initiation step? Does the platinum influences this or is it just due the weak bonding between Br-Br?
