Provide a mechanism for the entire reaction of 1,4-dimethoxybenzene + 3-methyl-2-butanol + Sulfuric Acid --> 1,4-dimethoxy-2,5-di-tert-pentylbenzene.
For a Friedel-Crafts alkylation reaction between 1,4-dimethoxybenzene with 3-methyl-2-butanol and sulfuric acid what product was formed in this reaction? Use a discussion of the reaction mechanism, IR, and NMR data to justify your conclusion. A figure should be included to aid in the discussion of the reaction mechanism.
Calculate the moles of 1,4-di-tert-butyl-2,5-dimethoxybenzene (0.500 mL) that 2-methyl-2-propanol would form if it were the limiting reactant. Use proper significant figures, units and show all work.

Provide structures for two compounds that could be used in place of tert-butyl alcohol to form 1,4-di-tert-butyl-2,5-dimethoxybenzene from 1,4- dimethoxybenzene via a Friedel-Crafts reaction:
Complete the mechanism for the reaction of 2-butanol in sulfuric acid at 140℃ by adding any missing atoms, bonds, charges, nonbonding electrons, and curved arrows. Note the use of a generic alcohol to represent another 2-butanol introduced in panel three.
QUESTIONS 1. What is the purpose of the sulfuric acid (yes, it's a catalyst, but why is it a catalyst? What is it doing that makes the reaction possible? Would the reaction just go slower without it, or would the reaction not go at all? Why?) 2. If isobutyl alcohol (2 methyl propanol) is used instead of tert butyl alcohol, a mixture of products is obtained. One the products is the same as the product obtained with the tert butyl...
These question are for the Friedel Crafts Alkylation of 1,4-Dimethoxybenzene organic chem lab 1. Why is 1,4-di-t-butyl-2,5-dimethoxybenzene the preferred product of this reaction? Why is neither 1,2-di-t-butyl-3,6-dimethoxybenzene nor 1,3-di-t-butyl-3,6-dimethoxybenzene formed as side products? OCH3 OCH3 OCH3 OCH3 1,2-di-t-butyl-3,6-dimethoxybenzene 1,3-di-t-butyl-3,6-dimethoxybenzene 2. 3. 4. Why was the product washed with water? Why was the product washed with methanol? We used t-butyl alcohol to generate t-butyl cation. Suggest two other compounds that could be used to generate the t-butyl cation.
