Chapter 21, Problem 21.8P

Interpretation Introduction

Interpretation:

The structure of a compound with the molecular formula ${\text{C}}_{\text{4}}{\text{H}}_{\text{9}}\text{NO}$ using the given NMR spectrum and IR data is 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.
