The antisymmetric -CH2-CO-O- stretching vibration in carboxylic acids is heavily mixed with the in-plane bending mode of the O-H group. In alcohols these two vibrations seldom show evidence of mechanical coupling. Explain.
The hydroxylamine I can be oxidized by MnO2 to the amide oxohaemanthidine (II). In dilute solution the carbonyl absorption band of II occurs at 1702/cm. Explain this observation.
