ons irse Question 1 You will eventually take an IR spectrum of the final product. What functional group shift would be most diagnostic for conversion of the s O The 9 and 10 position C-H bonds of anthracene will absorb at higher frequency in the product O The sp2 C-H bonds of maleic anhydride will absorb at a higher frequency in the product O The carbonyl peak from maleic anhydride should absorb at a higher frequency when converted to the product O none of these spectral changes will occur O all of these spectral changes will occur
