Chapter 15, Problem 48PP

 (a)

Interpretation Introduction

Interpretation: The number of signals and the chemical shift range of each signal to be predicted.

Concept Introduction:

The 13CNMR spectrum gives information on the different electronic environments of carbon. As like 1HNMR , the number of signals generated in 13CNMR are predicted by performing symmetry operations (rotation or reflection symmetry). Only chemical shift values are reported in the spectrum but not the multiplicity and integration values because the coupling between two neighboring 13C13C nuclei are weakly involved due to the low abundance of 13C isotopes of carbon atom.

Chemical shift range: The bench mark chemical shift region for the carbons of different electronic environments.
