Chapter 9, Problem 24P

Interpretation Introduction

Interpretation:

The structures for O and P are to be proposed on the basis of the given information.

Concept introduction:

In NMR, the chemical shift of the nucleus depends on the relative electron density around an atom. Attached with highly electronegative atoms means highly deshielded and higher will be the chemical shift value.

DEPT ${}^{13}\text{C}$ NMR spectra explains the number of atoms of hydrogen bonded to each carbon.
