Chapter 16.2, Problem 8P

Interpretation Introduction

Interpretation:

The appropriate carbonyl IR value for the given compound has to be matched.

Concept Introduction:

IR spectroscopy: IR spectrum provides the information regarding the functional groups a compound possesses.  When a molecule is bombarded with radiation of a frequency that exactly matches the frequency of the vibration of one of its bonds, the molecules absorbs energy.

Stretch vibrations: It is a vibration occurring along the line of the bond a stretching vibration changes the bond length.

Bending vibrations: It is a vibration that does not occur along the line of the bond, bending vibration changes the bond angle.
