Why does the expected stretching absorption of the C=O bond in compounds I and II differ, as shown below?




▸ Compound I has more possible resonance structures, increasing the single bond character of the carbonyl group.

▸ Compound II has more possible resonance structures, increasing the single bond character of the carbonyl group.

▸ Compound I has a C to O bond with more single bond character than that of compound II, increasing the expected stretching absorption of the bond.

▸ Only compound II has resonance, causing it to have a higher stretching absorption.

▸ Only compound I has resonance, causing it to have a higher stretching absorption.
