WebThe carbonyl stretch C=O of a carboxylic acid appears as an intense band from 1760-1690 cm -1. The exact position of this broad band depends on whether the carboxylic acid is saturated or unsaturated, dimerized, or has internal hydrogen bonding. O–H stretch from 3300-2500 cm -1 C=O stretch from 1760-1690 cm -1 C–O stretch from 1320-1210 cm -1 WebThe carbonyl stretching absorption is one of the strongest IR absorptions, and is very useful in structure determination as one can determine both the number of carbonyl groups …
WebAcetone (2-propanone) is the "classic" carbonyl containing compound with the obvious C=O stretch in the middle of the spectra. Note that the peak is a very strong absorption.
