Chapter 14.5, Problem 8CC

Interpretation Introduction

Interpretation:

The given condition that the alcohol group in IR spectrum shows broad signal which is always seems to appear on right side of the narrow signal should be explained.

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.

Hydrogen Bonding: The bonding that arises due to the force of electrostatic attraction between the hydrogen of one molecule to electronegative atom of other molecule.
