(a)

Interpretation Introduction

Interpretation:

The carbonyl group which produces signal at lower wavenumber in given compounds should be determined under given conditions.

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 ${\text{cm}}^{\text{-1}}$.

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

Conjugated Compounds: The conjugated compounds arises when the p-orbitals overlap bridges the single bonds lying between the two phi bonds, which allows the delocalization of electrons over the compound.
