Chapter 16, Problem 16.8P

Interpretation Introduction

Interpretation:

The structure of the compound having formula ${\text{C}}_{\text{7}}{\text{H}}_{\text{6}}{\text{OCl}}_{\text{2}}$ is to be predicted from the given illustration.

Concept Introduction:

The ${}^{\text{13}}\text{C}$ NMR spectroscopy is used to detect the presence of ${}^{\text{13}}\text{C}$ nucleus. The natural abundance of ${}^{\text{13}}\text{C}$ nucleus is only $1.1\%$ while ${}^{\text{12}}\text{C}$ nucleus is not detectable by NMR spectroscopy. The difference between its resonance frequency and that of the reference standard is known as the chemical shift of a nucleus. The $\left(n+1\right)$ rule is applicable on the protons attached to the same carbon whose splitting pattern is to be determined.
