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. At the same time they also show the … WebPopular answers (1) 11th Jul, 2015. N. Venkatathri. National Institute of Technology, Warangal.
