Chapter 13, Problem 13.42SP
Interpretation Introduction

Interpretation:

The structure of the given NMR spectrum is to be proposed and which carbon atom give rise to which peak in the spectrum is to be shown.

Concept introduction:

NMR spectroscopy is a technique used to determine a unique structure of the compounds. It identifies the carbon-hydrogen bonding of an organic compound. A hydrogen atom is called as a proton in the NMR spectroscopy.
