Chapter 12.SE, Problem 38AP

Interpretation Introduction

Interpretation:

The strongest bond has to be identified from C=O bond in an ester (1735 cm^-1) or the C=O bond in a saturated ketone (1715 cm^-1).

Concept introduction:

Spectroscopy:

It is study of the interaction of matter and electromagnetic radiation, a continuum of different types of electromagnetic radiation each associated with a particular energy range makes up the electromagnetic spectrum.

IR frequency (cm^-1):

It is the number of wave crests that pass by a given point in one second frequency has units of hertz (Hz).

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.

Given information:

The IR value is given below,
