As outlined in the Introductory Pages, draw a flow chart for the experiment and draw the mechanism for the formation of $1,4-$di$-$t$-$butyl$-2,5-$dimethoxybenzene from $1,4$dimethoxybenzene and $t-$butanol in the presence of sulfuric acid.

Pre Lab Questions

$1$ Why is the $1,4-$isomer, $1,4-$di$-$t$-$butyl$-2,5-$dimethoxybenzene, the major product in this reaction? Would you expect either of the following compounds to be formed as side products: $1,3-$di$-$t$-$butyl$-2,5-$dimethoxybenzene or $2,3-$di$-$t$-$butyl$1,4-$dimethoxy$-$benzene? Why or why not?

$2$ Suggest two compounds that might be used in place of $t-$butyl alcohol to form $1,4-$di$-$t$-$butyl$-2,5-$dimethoxybenzene from $1,4-$dimethoxybenzene.
