Chapter 17, Problem 17.9P

Interpretation Introduction

(a)

Interpretation: The position of protons bonded to the $s{p}^2$ hybridized carbons (absorbs in the ${}^1\text{H}$ NMR spectrum) in the ${}^1\text{H}$ NMR spectrum of given compound is to be estimated.

Concept introduction: The protons present on $s{p}^2$ hybridized carbons in aromatic hydrocarbon are highly deshielded and show absorption at $6.5-8\text{ ppm}$. The protons present in non aromatic hydrocarbon are highly shielded and show absorption at $4.5-\text{6 ppm}$.

Interpretation Introduction
