Friedel-Crafts alkylation of anisole (PhOCH3) with tert-butyl chloride [(CH3)3CCl] and AlCl3 gives mostly the para-substituted product. Explain this outcome by showing the complete step wise mechanisms for para and meta positions using the curved arrow notation. The mechanisms must include the formation of the electrophile, attack of the electrophile at the meta and para positions, as well as all stabilizing resonances of the arenium ions that are formed and their relative stability, and the final substitution products.
