WebThe bond energy (and force constant) of the conjugated C=O group is correspondingly reduced, and this results in a lower stretching frequency. 2. Under ideal conditions the carbon atom of a carbonyl group is essentially sp 2 hybridized, which implies that the bond angles will be 120° and the C-O sigma bond has 33% s-character.
