Question
Chapter 15.11B, Problem 15.17P
Interpretation Introduction
Interpretation: The charge-separated resonance form of the reactant that is given in solved problem
Concept introduction: The charge separated resonance is defined as the separation of positive and negative charge present on a molecule. The delocalization of lone pair or free electrons from one place to another is known as resonance. The stability of compound depends upon the number of resonating structures. More the resonating structures of compound more will its stability.
To draw: The charge-separated resonance form of the reactant that is given in solved problem

5 (a). Using the peak information you listed in the tables for
both structures, assign each peak to that portion of the
structure that produces the peak in the NMR spectrum. Draw
this diagram on your own sheet of paper and attach the sketch
of your drawing to this question.

- Interpreting NMR spectra is a skill that often requires some amount of practice, which, in turn, necessitates access to a collection of NMR spectra. Beyond Labz Organic Synthesis and Organic Qualitative Analysis have spectral libraries containing over 700 1H NMR spectra. In this assignment, you will take advantage of this by first predicting the NMR spectra for two closely related compounds and then checking your predictions by looking up the actual spectra in the spectra library. After completing this assignment, you may wish to select other compounds for additional practice. 1. Write the IUPAC names for the following two structures: Question 2 Question 3 2.
