Why is the expected stretching absorption of the C=O bond 1685 cm-1 for the structure I and 1715 cm-1 for structure II?



◦ Compound I lacks conjugation, which is present in compound II.
◦ The expected stretching absorption is lowered in all molecules with cyclohexane rings.
◦ Having fewer double bonds results in lowering of all of the stretching absorptions.
◦ The C to O double bond of compound I has greater single bond character than the C to O double bond of compound II.
◦ Compound II has a C to O double bond with considerable single bond character, lowering the expected stretching absorption.
