Chapter 22, Problem 22.81P

Interpretation Introduction

Interpretation: The protons of $2$-chloroacetamide that give rise to three signals at $4.02$, $7.35$ and $7.60\text{ppm}$ are to be identified and an explanation for the observation of three signals is to be stated.

Concept introduction: The method of spectroscopy is used to identify the structure of the molecule. It is based on the interactions between matter and electromagnetic radiations. Proton 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.
