Chapter 9, Problem 30P

Interpretation Introduction

Interpretation:

The structure of compound S $\left({\text{C}}_8{\text{H}}_{16}\right)$ is to be proposed.

Concept introduction:

A few elements such as ${}^{13}{\text{C\hspace{0.17em}and\hspace{0.17em}}}^1\text{H}$ have nuclei that behave as magnets about an axis, which are placed in a magnetic field irradiated with electromagnetic energy of a specific frequency. Then, the nuclei tend to absorb energy via magnetic resonance. The graph that shows energy absorption frequencies and intensities of a sample kept in the magnetic field is called nuclear magnetic resonance (NMR).

Chemical shift is the measurement on the $\delta$ scale (in ppm) where the peaks appear when the nuclei absorb energy through magnetic resonance.
