WebIf resonance is considered, then the resonance structure for an ester (11.42) is more important than that for the thioester (11.43) because there is little C–S π-bond character. In terms of inductive effects, oxygen is more electronegative than sulfur, so 11.45 is lower energy (more favorable) than 11.44; this enhances the acidity of the α-protons. how to use kreyol essence on hairWebEthyl propanoate is present in certain foods and participates actively in the digestion.
