Interpretation Introduction

Interpretation:

The statement that put incorrect interpretation with respect to the coupling of the proton that is present at $\text{C1}$ position of the geometrical isomers of $4-tert-\text{butylcyclohexanol}$ is to be identified.

Concept Introduction:

The spectral line of a proton in an NMR spectrum is appreciably affected by the chemical environment of its neighboring proton.

In NMR, it is observed that if a proton is surrounded by such protons that have different chemical environment then splitting of the NMR signal of that proton is taken place because of the spin-spin coupling of the proton with its neighboring protons.
