Chapter 18, Problem 46P

Interpretation Introduction

Interpretation:

The compound with a molecular formula ${\text{C}}_{\text{4}}{\text{H}}_{\text{8}}\text{O}$ containing carbonyl group has to be identified on the basis of its ${}^{\text{1}}\text{H}$ NMR spectrum shown in Figure 18.14.

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 NMR spectroscopy identifies the total 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.
