A) Deduce the structure of compound A. Draw all non-bonding electrons (as applicable) (b) Give a curved-arrow mechanism for the conversion of A into 3,6-dimethylphthalic anhydride. The catalyst H2SO4 is abbreviated as \"H–B\" below and its conjugate base is abbreviated as \":B–\". Follow the directions above each drawing box. First step: Delete/Add bonds to form A, Second step: Draw missing bond and Add 2 curved arrows to give next product. curved arrow.
