Propose three different fragmentation/rearrangement mechanisms for the molecular ion of the following molecule, formed in an electron ionisation mass spectrometer's source. Clearly indicate on the fragments whether they are free radicals, carbocations or radical cations. CI Instructions: Draw the mechanisms by hand using pen and paper and upload a single image (photograph) of your work into the "drag-and-drop" space below. Only an uploaded image of work done in your own handwriting will be graded.

Following is an equation for iodination of toluene. This reaction does not take place. All that happens under experimental conditions for the formation of radicals is initiation to form iodine radicals, I , followed by termination to reform I2. How do you account for these observations?
The aerobic oxidation of para-xylene to terephthalic acid is an important process in industrial chemistry. Discuss why the oxidation of the second methyl group requires harsher conditions than the oxidation of the first methyl group. You should accurately reference all your bibliographic material.
As in the free-radical halogenation of alkanes, chlorination of alkylbenzenes is less selective than bromination. Given the relative rates per hydrogen for hydrogen atom abstraction from 1-phenylbutane by chlorine for the elementary step shown, calculate the percentage of 1-chloro-1-phenylbutane in the C10H13Cl product.
2,2-dimethylpropane only reacts with bromine in a solvent of CCl4. The presence of sunlight is required in this reaction. Specify the type of reaction and show the complete mechanism for the reaction occurred. This is a free radical halogenation, however I don't understand what it meant by "only recats with bromine in a solvent of CCL4"... can I have some explanation :(
In copolymerization of two monomers (M1 and M2), copolymers of different microstructure may form as a result of their relative reactivity ratio (r). Define the reactivity ratio (r) for copolymerization with words and equations. In the radical copolymerization of acrylonitrile 1 and alpha methyl styrene 2 , r1= 0.04 and r2= 0.20 , which of the following best describes the microstructure of the forming copolymer : random, blocky or alternating. Briefly explain it
Provide the mechanisms for chlorination of toluene which include the initiation, propagation and termination steps
I am not sure how they got 10 ns^-1, this is occurring at SATP conditions. .
need help with this ASAP pls & thank you! (it's asking for you to fill in the blank boxes)
INSTRUCTIONS - Given in each item is a reaction scheme showing the reactant/s, reagent/s, and major product. If the compound shown at the right side is not the major product, rewrite the scheme to show the correct product/s. - Propose a feasible mechanism for each reaction. - Observe the proper construction of reaction mechanisms (arrow positioning, types of arrow heads, lone pair electrons, charges, entry/exit of chemical species, etc.). You may also provide a brief explanation (NMT 5 sentences) for your answer. - Stereoselectivity and regioselectivity of reactions must be observed, whenever applicable. Show the stereochemistry of the compounds using solid- and hashed-wedged bonds. Incorrect isomers will not be considered.
CH.8 #8 - Please fill in the blank, cirlce your answer for thumbs up!
Write a pair of chain propagation steps for the radical bromination of propane to give 1-bromopropane. Then calculate ▲H° for each propagation step and for the overall reaction.
With regards to this, I have been reading journals about activated carbon that is being modified. Now, the activated carbon is modified through acid treatment, and sulfuric acid is added to it. The result was, that there is a presence of SO3-, C=O=C, and C=O on the modified activated carbon. They concluded that the process of sulfonation on the activated carbon treated with sulfuric acid took place. Can you explain the chemistry/mechanism/reaction that happened? Explain in detail and clearly. Thank you so much!
