Interpretation Introduction

(a)

Interpretation:

The effect of spin-spin coupling on the proton NMR absorptions of butane is to be predicted. The way by which butane can be diffrentiated from cyclobutane and isobutane (2 methylpropane) is to be stated.

Concept introduction:

Spectroscopy based on the splitting of Ml levels of a nuclei is termed as nuclear magnetic resonance or NMR. The splitting is dur to the similar behaviour of nucleus as the electron. Like electrons, nucleus have nonzero spin and a magnetic dipole associated with it. This leads to splitting in an external magnetic field.

Interpretation Introduction
