Chapter 23, Problem 50A

a)

Interpretation Introduction

Interpretation: To classify the compounds as alcohol, phenol, or ether.

Concept Introduction: The functional group in a molecule will indicate the behavior and chemical reactions of the molecule. The presence of the functional group will help in characterizing the compound.

Answer to Problem 50A

  

The given molecule is a phenol.

Explanation of Solution

The given molecule contains two aromatic rings. One aromatic ring has an OH group attached to it hence this group is named as phenol group. The given molecule contains the phenol group so the given molecule belongs to the phenol group.

b)

Interpretation Introduction

Interpretation: To classify the compounds as alcohol, phenol, or ether.

Concept Introduction: The functional group in a molecule will indicate the behavior and chemical reactions of the molecule. The presence of the functional group will help in characterizing the compound.

Answer to Problem 50A

  

The given compound belongs to ether.

Explanation of Solution

The given compound is in the form of ${\text{ROR}}^{\text{'}}$ in which both the R groups are the phenyl groups. Since the given compound is ether, it is named as Diphenyl ether.

c)

Interpretation Introduction

Interpretation: To classify the compounds as alcohol, phenol, or ether.

Concept Introduction: The functional group in a molecule will indicate the behavior and chemical reactions of the molecule. The presence of the functional group will help in characterizing the compound.

Answer to Problem 50A

  

The given compound belongs to alcohol.

Explanation of Solution

The given compound is in the form of ROH. In this the functional group is alcohol. Therefore, the given compound belongs to the class of alcohol.

d)

Interpretation Introduction

Interpretation: To classify the compounds as alcohol, phenol, or ether.

Concept Introduction: The functional group in a molecule will indicate the behavior and chemical reactions of the molecule. The presence of the functional group will help in characterizing the compound.

Answer to Problem 50A

  

The given compound belongs to the Phenol group.

Explanation of Solution

The given molecule contains aromatic rings. The aromatic ring has an OH group attached to it hence this group is named as phenol group. The given molecule contains the phenol group so the given molecule belongs to the phenol group

e)

Interpretation Introduction

Interpretation: To classify the compounds as alcohol, phenol, or ether.

Concept Introduction: The functional group in a molecule will indicate the behavior and chemical reactions of the molecule. The presence of the functional group will help in characterizing the compound.

Answer to Problem 50A

  

Explanation of Solution

The given alcohol has an OH group in the given compound. Since there is a presence of alcohol in the given compound it comes under the class of the alcohol group.

f)

Interpretation Introduction

Interpretation: To classify the compounds as alcohol, phenol, or ether.

Concept Introduction: The functional group in a molecule will indicate the behavior and chemical reactions of the molecule. The presence of the functional group will help in characterizing the compound.

Answer to Problem 50A

  

The given compound belongs to the group of Ether.

Explanation of Solution

The given compound is in the form of ${\text{ROR}}^{\text{'}}$ in which one of the R and ${\text{R}}^{\text{'}}$ group are the alkyl group. One of the alkyl chains will be shorter and the other alkyl chain will be longer. Therefore, the given compound belongs to ether.
