Chapter 22.1, Problem 6SSC

Interpretation Introduction

(a)

Interpretation:

The functional group, name of the group and the type of the organic compound ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}\text{OH}$ needs to be determined.

Concept introduction:

The functional group is the group present on the main carbon chain of an organic compound. It determines the chemical properties and the type of reactions an organic compound can show. The name of the group depends on the atoms present in the group for example an −OH group contains O and H atom thus, it is a hydroxyl group. The different functional groups are named according to IUPAC rule.

Name of some functional groups are: -OH: alcohol, -CHO: aldehyde, -COOH: carboxylic acid etc.

Answer to Problem 6SSC

Functional group: -OH

Name of the group: -hydroxyl

Type of the organic compound-Alcohol

Explanation of Solution

The given organic compound is as follows:

${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}\text{OH}$

There are 3 carbon atoms and one −OH group present in it. Here, -OH group is functional group. The name of the group is hydroxyl. This is the functional group for alcohol. Therefore, the type of the organic compound is alcohol.

Interpretation Introduction

(b)

Interpretation:

The functional group, name of the group and the type of the organic compound ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{F}$ needs to be determined.

Concept introduction:

The functional group is the group present on the main carbon chain of an organic compound. It determines the chemical properties and the type of reactions an organic compound can show. The name of the group depends on the atoms present in the group for example an −OH group contains O and H atom thus, it is a hydroxyl group. The different functional groups are named according to IUPAC rule.

Name of some functional groups are: -OH: alcohol, -CHO: aldehyde, -COOH: carboxylic acid etc.

Answer to Problem 6SSC

Functional group: -F

Name of the group: -halide

Type of the organic compound-alkyl halide

Explanation of Solution

The given organic compound is as follows:

${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{F}$

There are 2 carbon atoms and one −F group present in it. Here, -F group is functional group. The name of the group is halide. This halide group is present on the alkane. Therefore, the type of the organic compound is alkyl halide.

Interpretation Introduction

(c)

Interpretation:

The functional group, name of the group and the type of the organic compound ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{NH}}_{\text{2}}$ needs to be determined.

Concept introduction:

The functional group is the group present on the main carbon chain of an organic compound. It determines the chemical properties and the type of reactions an organic compound can show. The name of the group depends on the atoms present in the group for example an −OH group contains O and H atom thus, it is a hydroxyl group. The different functional groups are named according to IUPAC rule.

Name of some functional groups are: -OH: alcohol, -CHO: aldehyde, -COOH: carboxylic acid etc.

Answer to Problem 6SSC

Functional group: - ${\text{NH}}_{\text{2}}$

Name of the group: -amino

Type of the organic compound-amine or primary amine

Explanation of Solution

The given organic compound is as follows:

${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{NH}}_{\text{2}}$

There are 2 carbon atoms and one − ${\text{NH}}_{\text{2}}$ group present in it. Here, − ${\text{NH}}_{\text{2}}$ group is functional group. The name of the group is amino. This amino group is present on the alkane. Therefore, the type of the organic compound is amine and specifically primary amine.

Interpretation Introduction

(d)

Interpretation:

The functional group, name of the group and the type of the organic compound ${\text{CH}}_{\text{3}}\text{COOH}$ needs to be determined.

Concept introduction:

The functional group is the group present on the main carbon chain of an organic compound. It determines the chemical properties and the type of reactions an organic compound can show. The name of the group depends on the atoms present in the group for example an −OH group contains O and H atom thus, it is a hydroxyl group. The different functional groups are named according to IUPAC rule.

Name of some functional groups are: -OH: alcohol, -CHO: aldehyde, -COOH: carboxylic acid etc.

Answer to Problem 6SSC

Functional group: - $\text{COOH}$

Name of the group: -carboxyl

Type of the organic compound: carboxylic acid.

Explanation of Solution

The given organic compound is as follows:

${\text{CH}}_{\text{3}}\text{COOH}$

There are 2 carbon atom in the chain including 1 − $\text{COOH}$ group. Here, − $\text{COOH}$ group is functional group. The name of the group is carboxyl. This carboxyl group is an acidic group present on the alkane. Therefore, the type of the organic compound is carboxylic acid.
