Chapter 16, Problem 16.60P

Interpretation Introduction

Interpretation:

The splitting pattern for the highlighed proton B in the given molecule is to be drawn based on the coupling constant of 7 Hz between protons A and B and 16 Hz between protons B and C.

Concept introduction:

When a proton is coupled to more than one type of structurally distinct protons, the splitting pattern cannot be predicted by the $\text{n+1}$ rule. Each structurally distinct coupled proton independently splits the signal. In effect, the splitting by one type is superimposed on the splitting by the other.
