Chapter 22, Problem 54P

Interpretation Introduction

Interpretation:

The compounds A and B that are isomeric amines of molecular formula ${\text{C}}_{\text{8}}{\text{H}}_{\text{11}}\text{N}$ are to be identified on the basis of their ${}^{\text{1}}\text{H}$ NMR spectrum.

Concept introduction:

Spectroscopy is a method that 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.
