Chapter 13, Problem 13.22P
Interpretation Introduction

(a)

Interpretation:

The structures of two isomeric alkyl halides having molecular formula C5H11Br using the NMR data are to be stated.

Concept introduction:

Many nuclei and electrons have spin. Due to this spin magnetic moment arises. The energy of this magnetic moment depends on the orientation of the applied magnetic field. In NMR spectroscopy, every nucleus has a spin. There is an angular momentum related to the spin. The difference between its resonance frequency and that of the reference standard is known as the chemical shift of a nucleus. Tetramethylsilane (TMS) is taken as reference.

Interpretation Introduction

(b)

Interpretation:

The change in the NMR spectrum of the compound A if the spectrum is taken at 600MHz is to be stated.
