The C–O absorption in carboxylic acids appears around 1250 cm-1.  The C–O absorption in an alcohol appears around 1050 cm-1. Explain why.




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

▸ 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.

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