Chapter 16, Problem 16.4P

Interpretation Introduction

Interpretation:

From the given figure 16-5, it is to be explained if protons in benzene are chemically equivalent to those in TMS.

Concept introduction:

Protons that reside in identical chemical environments, called homotopic protons or chemically equivalent protons, absorb, at the same RF frequency, one signal in a proton NMR spectrum.

Each chemically distinct type of hydrogen atom in a molecule gives rise to an independent signal in a proton NMR spectrum.
