"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). " - O-o stretching frequency
