Chapter 21.2, Problem 7P

Interpretation Introduction

Interpretation:

An explanation corresponding to the fact that the compound, $\text{1-}\left(\text{3,4-dimethoxyphenyl}\right)\text{propan-2-one}$ on heating with ${\text{D}}_{\text{2}}\text{O}$ containing ${\text{K}}_{\text{2}}{\text{CO}}_{\text{3}}$ shows signals for the protons in the ${\text{OCH}}_{\text{3}}$ group and for those on the aromatic ring only in its ${}^{\text{1}}\text{H}$ NMR spectrum is to be stated.

Concept introduction:

In carbonyl compounds, the protons present on their $\text{α}$ carbon atoms are found to be most acidic in nature and are commonly called as $\text{α}$ protons.

Proton NMR spectroscopy identifies the amount of hydrogen atoms present in a molecule and the nature of the functional group.

The value of chemical peaks based upon the chemical environment around the hydrogen atom.
