The IR spectra of the following compo After a chemical reaction was performed on this compe disappeared and was replaced by a strong products agrees with this experimental data? (6 points) compounds should a strong broad signal centered at 3520 d by a strong signal at 1720. Which set of reactants and this compound the signal at 3520 had OH OH 6. AC' spectrum of an aromatic di-halide showed 4 carbon signals in the aromatic region of the spectra. Which of the following structures is constant with this data? o pomis)
