Question
Chapter 19, Problem 19.38QAP
Interpretation Introduction
Interpretation:
The way by which a band of frequencies is obtained from an oscillator should be predicted. The reason for the broadening of band is enough to cover the entire
Concept introduction:
Nuclear magnetic reasonance is a technique that is used to predict the structural formula of the compound. NMR spectroscopy involves the examination of the nucleus under the external magnetic field.

Some important notes:
• Draw the major product, or products, of the reaction in the drawing area below.
• If there aren't any products, because no reaction will take place, check the box below the drawing area instead.
• Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are
enantiomers.
