Chapter 14.13, Problem 29CC

(a)

Interpretation Introduction

Interpretation: For the given set of compounds the difference between them should be determined.

Concept Introduction:

IR spectral studies: It is a spectroscopic technique which is used to determine the functional groups present in the given compound sample by absorbing frequency in particular range with respect to the group present in the given sample.

Wavenumber: It is defined as the number of waves in one centimeter. The wavenumber indicates the location of each signal with respect to the functional group in the molecule and its unit is ${\text{cm}}^{\text{-1}}$.

Alcohol functional group: It refers to the functional group that contains one $\text{OH}$ group bonded with the carbon atom in a molecule. The characteristic IR signal for $\text{OH}$ group is broad signal at range of about 3200-3600 ${\text{cm}}^{\text{-1}}$.

Carbonyl group: The functional group that contains carbon atom which is doubly bonded with the oxygen atom.
