Chapter 13.9, Problem 13.12P

Interpretation Introduction

Interpretation: The splitting tree and the chemical shift of protons ${\text{H}}_{\text{c}}$ in styrene are to be determined.

Concept introduction: The chemical shift is defined as the difference in parts per million in the absorption spectrum of a particular proton from the absorption position of a reference proton. Tetramethylsilane is taken as the reference proton. Chemical shifts are measured in parts per million and it is a dimensionless quantity.

To determine: The splitting tree and the chemical shift of protons ${\text{H}}_{\text{c}}$ in styrene
