The plot displays the infrared absorption spectrum, with the x-axis labeled as "wavenumber (cm⁻¹)" ranging from 4000 to 600 cm⁻¹, and the y-axis showing absorption from 0 to 100%. The graph indicates various peaks, which correspond to different functional groups present in a molecule.**Compounds:**Five molecular structures are provided below the graph. Identify which structure corresponds to the given spectra based on the absorption bands identified earlier.- **Compound A**: Features a hydroxyl (OH) group.- **Compound B**: Contains ethyl and ketone groups.- **Compound C**: Shows carboxylic acid functionality.- **Compound D**: Comprises a phenyl ring with an alcohol group.- **Compound E**: Includes a nitrile (CN) group.Use this information to complete your analysis of the infrared spectra.
