a) Show the mechanism for the free radical chlorination of bromopropane. Clearly show the initiation, propagation, and termination steps. b) Use the BDEs shown on page 1 to calculate the enthalpy change for this reaction. c) Unfortunately, the student’s attempt in question 3 failed, and he only made traces of 2- chloropropane by using this approach. What was the major product of the reaction, and explain why it was formed instead. You may find the BDEs on page 1 to...

pleas help 5,6,7,8,9,10 III IV 5. The product of free-radical halogenation reactions is an alkyl halide. The major amount of this halide forms during the second step of propagation. However, you should be aware that one possible termination step also forms alkyl halides. Why does the majority of the alkyl halide product come from the propagation step and not the termination step? A. At any given time during the reaction, the concentration of both the alkyl radical and the halide...

If there isa possibility of rearrangement, please show it for the major product CH3 39. Propose a detailed, step-by-step mechanism for the reaction pathway shown below. 40. CH,CH,CH,Br+NaCCC 41. Plcase draw a plausible reaction mechanism of the following free radical reaction by showing the initiation step, propagation step, and termination step. Bry
Shown below is an alternative mechanism for the photochemical chain radical chlorination of methane: Cl_2 + CH_4 right arrow CH_3CI + HCL Step 1 (initiation): CI_2 right arrow 2CI- Step 2 (propagation, part 1): CI +CH_4 right arrow CH_3CI + H Step 3 (propagation, part 2): H + CI_2 right arrow HCI +CI. Using the data provided below(bond dissociation energies, BDE), calculate delta Hdegree for each of the two propagation steps of the alternative mechanism. BDE: C-H bond, 104kcal/mol; C-Cl...
For the following reaction give the detailed mechanism in terms of: electron flow energy diagram, put both propagation step 1 and step 2 on the same diagram CH3--CH3 + Br2 ------> CH3CH2--Br + HBr This is what I have so far, and I think I'm correct. Im having trouble with the energy diagram. Initiation Br--Br ---> 2 Br . (dot symbolizes radical) Propagation (step 1) Br . + H--CH2--CH3 ---><---- Br-H + . CH2--CH3 Propagation (step 2) . CH2--CH3 +...
