WebAs we do this, the hybridization of the orbitals the carbonyl carbon uses to form these bonds changes from s p X 2 to p. As these bonds use more p-character, more s-character remains for use in the C-O sigma bond. This would strengthen the CO bond and raise the energy required to stretch it (increase its ir stretching frequency). 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.
