Chapter 14, Problem 14.75P

Interpretation Introduction

Interpretation: An explanation for the two nonequivalent ${\text{CH}}_{\text{3}}$ groups in N, N-dimethylformamide to each other, thus giving rise to two NMR signals in ${}^1\text{H}\text{NMR}$ is to be stated.

Concept introduction: Spectroscopy method is used to identify the structure of the molecule. It is based on the interactions between matter and electromagnetic radiations. Proton $\text{NMR}$ spectroscopy identifies the number of hydrogen atoms present in a molecule and the nature of the functional group. The value of chemical peaks depends upon the chemical environment around the hydrogen atom.
