Abstract A Friedel-Crafts alkylation was performed by adding t-butyl alcohol to p-dimethoxybenzene in order to produce 1‚4-di-t-butyl-2‚5-dimethoxybenzene. This reaction yielded 0.009g of 1‚4-di-t-butyl-2‚5-dimethoxybenzene having a percent yield of 5%‚ and a melting point range of 54.8°C-56.9°C. Introduction This reaction is designed to put functional groups onto aromatic rings. This is done through an electrophilic aromatic substitution where a positive species is strong enough to pull electrons
