Characteristic IR Absorptions of Some Functional Groups In the box provided, write the IR frequency or range of frequencies that would best distinguish between the two compounds shown. Specify which compound (A or \( B \) ) will display a band at this frequency in its IR spectrum. (Choose the most prominent frequency. Do not include units in your answer. Use only the frequencies listed in the table given above. Write the letter of the compound, followed by the range of frequencies, separated by a comma. Example. "A, 1600 \( \left.1850^{4}\right) \) Compound ( \( A \) or \( B) \), IR frequency or range of frequencies: \( \mathrm{cm}^{-1} \)
