Polymersti 2. 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...
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?
I had a question regarding free radical substitution reaction (initiation, propagation, and termination). How do you form CH2 = CH2 ??? I believe this is formed in the termination step but how is it? Could you please show the steps so I can understand and learn. I will rate! Please answer ASAP. Thank You
