Chapter 23.1, Problem 4LC

a)

Interpretation Introduction

Interpretation : To identify the functional group in each of the following compounds and classify them based on the functional group.

Concept Introduction : Functional groups are set of molecules/atoms that are attached to another molecule and define the properties of that particular molecule.

Answer to Problem 4LC

Since the molecule has an attached OH group, it belongs to the alcohol family of compounds.

Explanation of Solution

For alcohol groups, the general formula is ROH. Here R is ${\text{CH}}_{\text{3}}$ group that is attached to -OH group. Thus, the compound belongs to the Alcohol family of compounds.

b)

Interpretation Introduction

Interpretation : To identify the functional group in each of the following compounds and classify them based on the functional group.

Concept Introduction : Functional groups are set of molecules/atoms that are attached to another molecule and define the properties of that particular molecule.

Answer to Problem 4LC

Since the molecule has attached ${\text{NH}}_{\text{2}}$ group, it belongs to the amine family of compounds.

Explanation of Solution

For amine groups, the general formula is ${\text{RNH}}_{\text{2}}$ . Here R is the ${\text{C}}_{\text{2}}{\text{H}}_{\text{5}}$ group attached to ${\text{NH}}_{\text{2}}$ group. Thus, the compound belongs to the Amine family of compounds.

c)

Interpretation Introduction

Interpretation : To identify the functional group in each of the following compounds and classify them based on the functional group.

Concept Introduction : Functional groups are set of molecules/atoms that are attached to another molecule and define the properties of that particular molecule.

Answer to Problem 4LC

Since the molecule is in the form of RCOOH group, it belongs to the Carboxylic acid family of compounds.

Explanation of Solution

For Carboxylic groups, the general formula is RCOOH. Here R is the Benzene group attached to COOH. Thus, the compound belongs to the Carboxylic family of compounds.

d)

Interpretation Introduction

Interpretation : To identify the functional group in each of the following compounds and classify them based on the functional group.

Concept Introduction : Functional groups are set of molecules/atoms that are attached to another molecule and define the properties of that particular molecule.

Answer to Problem 4LC

Since the molecule has an attached Br group, it belongs to the Halo Alkanes family of compounds.

Explanation of Solution

Halo Alkanes are chemical compounds that contain an alkane along with a halogen where one or more hydrogen is replaced.

e)

Interpretation Introduction

Interpretation : To identify the functional group in each of the following compounds and classify them based on the functional group.

Concept Introduction : Functional groups are set of molecules/atoms that are attached to another molecule and define the properties of that particular molecule.

Answer to Problem 4LC

It is in the general formula ROR which is the general formula for ether. So, the compound belongs to the family of ethers.

Explanation of Solution

For Ether groups, the general formula is ROR. Here R which is C2H5 is attached to O to for ROR bound.

f)

Interpretation Introduction

Interpretation : To identify the functional group in each of the following compounds and classify them based on the functional group.

Concept Introduction : Functional groups are set of molecules/atoms that are attached to another molecule and define the properties of that particular molecule.

Answer to Problem 4LC

Since the molecule has attached, I group, it belongs to the Halo Alkanes family of compounds.

Explanation of Solution

Halo Alkanes are chemical compounds that contain an alkane along with a halogen where one or more hydrogen is replaced.
