Chapter 26, Problem 97FP

Interpretation Introduction

(a)

Interpretation:

Corresponding range of wavelength and frequencies should be calculated for given wavenumbers.

Concept introduction:

$\begin{array}{l}\text{Wave number =}\frac{1}{\text{wave length }}\\ \\ \text{C = }\lambda \upsilon \\ \lambda =\text{wave length}\\ \upsilon \text{=frequency}\end{array}$

Interpretation Introduction

(b)

Interpretation:

The bonds responsible for the absorptions labeled A, B, C, and D in the two infrared spectrashown here should be identified.

One spectrum is for acetone and the other spectrum is for 1-propanol, both of which are colorless liquids. From the two spectra, the spectra of acetone should be determined.

Concept introduction:

Acetone; - has one C=O bond, 2 C-C bonds, 6 C-H bonds.

1-propanol; - has one C-O bond, 2 C-C bonds, 7 C-H bonds and one O-H bond.

Interpretation Introduction

(c)

Interpretation:

The structure of the compound should be determined on the basis of given information:
