Chapter 10.22, Problem 31P

(a)

Interpretation Introduction

Interpretation:

The number of signals expected in the ${}^{\text{1}}\text{H}$ NMR spectrum of the given molecule has to be identified.

Concept Introduction:

${}^{\text{1}}\text{H}$ NMR spectroscopy:

It is the study of the interaction between electromagnetic radiation and the nuclei of hydrogen atoms.

Chemical equivalence:

The number of different kinds of protons in different electronic environments causes the number of signals in a ${}^{\text{1}}\text{H}$ NMR spectrum.

If the protons are in identical electronic environments, then they are said to be chemically equivalent and they produce only one signal.

(b)

Interpretation Introduction

Interpretation:

The number of signals expected in the ${}^{\text{1}}\text{H}$ NMR spectrum of the given molecule has to be identified.

Concept Introduction:

${}^{1}H$ NMR spectroscopy:

It is the study of the interaction between electromagnetic radiation and the nuclei of hydrogen atoms and the hydrogen atoms.

Chemical equivalence:

It is the study of the interaction between electromagnetic radiation and the nuclei of hydrogen atoms and the hydrogen atoms

If the protons are in identical electronic environments, then they are said to be chemically equivalent and they produce only one signal.
