WebIR SPECTRUM OF A CARBOXYLIC ACID A carboxylic acid functional group combines the features of alcohols and ketones because it has both the O-H bond and the C=O bond. Therefore carboxylic acids show a very strong and broad band covering a wide range between 2800 and 3500 cm-1 for the O-H stretch. WebJul 1, 2024 · The IR spectrum of phenols the O-H stretch appears at roughly 3500 cm -1. In addition, the IR spectra will show the bands typical for aromatic compounds in the region of 1500-1600 cm -1.
