Chapter 12C.3, Problem 9P

Interpretation Introduction

(a)

Interpretation: The protons on the highlighted carbons of the given compound that absorbs farther downfield are to be identified.

Concept introduction: Depending upon the electron density or the concentration of electron around the proton the chemical shift values of the proton varies relative to the reference signal. The terms, upfield and downfield expresses the relative location of signals. The meaning of upfield is to the right and of downfield is to the left.
