Chapter 18, Problem 48P

Interpretation Introduction

Interpretation:

The structure of the isomeric diketones on the basis of the given molecular formula $\left({\text{C}}_6{\text{H}}_{\text{10}}{\text{O}}_2\right)$ and their ${}^{\text{1}}\text{H}$ NMR spectrum data is to be identified.

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 number of hydrogen atoms present in a molecule and the nature of the functional group.

The value of chemical peaks in NMR depends upon the chemical environment around the hydrogen atom.
