Homework Help: Nedd help with Friedel Crafts alkylation

    Need help with Friedel Crafts alkylation

    Hi. In my laboratory text book there is an explanation on how to make 1,4-Di-t-butyl-2,5-dimethoxybenzene from p-Dimethoxybenzene, tert-butanol and sulfuric acid. I am to put acetic acid and t-butyl alcohol to the p-Dimethoxybenzene. What my textbook doesn't explain is what does the acetic acid do in the reaction. Could someone please explain to me.
    Thanks.

    Swatch, do you know what is the attacking electrophile in this reaction?

    The attacking electrophile would be the tert-butyl since the sulfuric acid protonated the tert-butanol and water leaves. Is that not correct?

    Yes, that's is true.
    I think that the acetic acid is used as a solvent in this reaction.Generally, acetic acid readily mixes with many other polar and non-polar solvents such as water, chloroform, and hexane.
