2
Step-by-step solution
The given reaction is a Friedel-Crafts acylation of anisole (methoxybenzene) with succinic anhydride. Succinic anhydride reacts with the Lewis acid catalyst AlCl ₃ to undergo ring opening, generating an electrophilic acylium ion intermediate: ⁺ C (= O ) CH ₂ CH ₂ COOAlCl ₃⁻ . The - OCH ₃ group on anisole is a strong electron-donating group via resonance ( +R effect), which activates the benzene ring towards electrophilic aromatic substitution and directs the incoming electrophile to the ortho and para positions.
