A chemist performed a reaction of 2-methylpent-2-ene with HBr in diethyl ether. However, after completing the reaction, she became concerned about the ether she had used as a solvent. Sometimes ethers can contain peroxides which form radicals. Unfortunately, radicals can impact the product of the reaction. Use the 'H NMR data to determine the result of this reaction.

Electrophilic Aromatic Substitution: Friedel-Crafts Alkylation please include experimental literature

5. Optically pure 2-octyl sulfonate was treated with varying mixtures of water and dioxane, and the optical purity of the resulting product (2-octanol) was found to vary with the ratio of water to dioxane, as shown in the following table (J. Am. Chem. Soc. 1965, 87, 287-291). Given that dioxane possesses fairly nucleophilic oxygen atoms, provide a complete mechanism that explains the variation in in the product's optical purity due to changes in solvent composition. Hint, the solvent is doing more here than just dissolving.. it is partaking in the reaction. Solvent Ratio (water : dioxane) 25:75 50: 50 75: 25 100 :0 Optical purity of (S)-2-octanol 77% 88% 95% 100% H20 он (R)-2-Octyl sulfonate (optically pure) (S)-2-Octanol (dioxane)

Give a detailed mechanism including all resonance isomers for intermediates (show electron flow) for the Friedel-Crafts reaction Expt. 29.4-micro: Friedel-Crafts Synthesis of 1,4-t-Butyl-2,5-dimethoxybenzene.  NOTE:  It is likely the mechanism from reactants to only 1-t-butyl-2,5-dimethoxybenzene.  I want a complete mechanism showing all steps and resonance isomers for the synthesis of the dialkylated product.
