Answer 1

Answer #1

3530 cm^-1 stretching frequency belongs to OH stretch and carbonyl stretch at 1740 cm^-1 indicates it is 3-hydroxy-2-butanone.

Spectrum 1 it is primary amide ( above 3000 two peaks and carbonyl stretch splitting indicates it is a primary amide)

Spectrum 2 is 3-hydroxy butanone.

Spectrum 4 OH stretch is absent.

Spectrum 3 dont have carbonyl stretch.

3. (3 pts.) Shown below is the IR spectrum 2-acetylcyclohexanone (the structure is provided in the spectrum). 2- acetylcyclohexanone exists as an equilibrium mixture of diketone and two enol forms. Both the diketone and enol forms can be seen in the provide IR spectrum, although the 2 different enols cannot be distinguished. The IR spectra of both enols is essentially identical and so do not be concerned with distinguishing the enols, just assign peaks to a “generic" enol. On the...
