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 :(
R. Atkinson (J. Phys. Chem. Ref. Data 26, 215 (1997)) has reviewed a large set of rate constants relevant to the atmospheric chemistry of volatile organic compounds. The recommended rate constant for the bimolecular reaction of O2 with an alkyl radical R at 298 K is 4.7 × 109 dm3 mol−1 s−1 for R = C2H5 and 8.4 × 109 dm3 mol−1 s−1 for R = cyclohexyl. Assuming no energy barrier, compute the steric factor, P, for each reaction. Hint: Obtain collision diameters from collision cross-sections of similar molecules in the Resource section.
As we will learn, many antioxidants–compounds that prevent unwanted radical oxidation reactions from occurring–are phenols, compounds that contain an OH group bonded directly to a benzene ring.a.) Explain why homolysis of the O–H bond in phenol requiresconsiderably less energy than homolysis of the O–H bond in ethanol(362 kJ/mol vs. 438 kJ/mol).b.) Why is the C–O bond in phenol shorter than the C–O bond in ethanol?
