Chapter 4, Problem 39PP

(a)

Interpretation Introduction

Interpretation:

The name of the Parent chain for the given compound should be identified.

Concept introduction:

Parent chain is the longest chain of a compound. If there are two longest chains, the more substituted chain is the parent chain.

Name for the alkane parent chain depends on the number of carbon atoms present in the longest continuous carbon chain.

Number of carbon atoms	Name of parent alkane
1	methane
2	ethane
3	propane
4	butane
5	Pentane
6	hexane
7	Heptane
8	octane
9	nonane
10	decane

Answer to Problem 39PP

Octane

Explanation of Solution

The longest chain of the given compounds is identified by counting the number of carbon atoms presented in each chain of a compound. Longest chain is the carbon skeleton of a molecule that contains more number of carbons.

The longest chain has eight carbon atoms. By referring the above table, deduce the name as octane for parent chain.

(b)

Interpretation Introduction

Interpretation:

The name of the Parent chain for given compounds should be identified.

Concept introduction:

Parent chain is the longest chain of a compound. If there are two longest chains, the more substituted chain is the parent chain.

Name for the alkane parent chain depends on the number of carbon atoms present in the longest continuous carbon chain.

Number of carbon atoms	Name of parent alkane
1	methane
2	ethane
3	propane
4	butane
5	Pentane
6	hexane
7	Heptane
8	octane
9	nonane
10	decane

Answer to Problem 39PP

Nonane

Explanation of Solution

The longest chain of the given compounds is identified by counting the number of carbon atoms presented in each chain of a compound. Longest chain is the carbon skeleton of a molecule that contains more number of carbons.

The longest chain has nine carbon atoms. By referring the above table, deduce the name as nonane for parent chain.

(c)

Interpretation Introduction

Interpretation:

The name of the Parent chain for given compounds should be identified.

Concept introduction:

Parent chain is the longest chain of a compound. If there are two longest chains, the more substituted chain is the parent chain.

Name for the alkane parent chain depends on the number of carbon atoms present in the longest continuous carbon chain.

Number of carbon atoms	Name of parent alkane
1	methane
2	ethane
3	propane
4	butane
5	Pentane
6	hexane
7	Heptane
8	octane
9	nonane
10	decane

Answer to Problem 39PP

Octane

Explanation of Solution

The longest chain of the given compounds is identified by counting the number of carbon atoms presented in each chain of a compound. Longest chain is the carbon skeleton of a molecule that contains more number of carbons.

Here there are two longest chain of carbon atoms presented. But one has one substituent and other has two substituents. So the two substituted longest chain is the parent chain.

The longest chain has eight carbon atoms. By referring the above table, deduce the name as octane for parent chain.

(d)

Interpretation Introduction

Interpretation:

The name of the Parent chain for given compounds should be identified.

Concept introduction:

Parent chain is the longest chain of a compound. If there are two longest chains, the more substituted chain is the parent chain.

Name for the alkane parent chain depends on the number of carbon atoms present in the longest continuous carbon chain.

Number of carbon atoms	Name of parent alkane

7	Heptane
8	octane
9	nonane
10	decane

Answer to Problem 39PP

Heptane

Explanation of Solution

The longest chain of the given compounds is identified by counting the number of carbon atoms presented in each chain of a compound. Longest chain is the carbon skeleton of a molecule that contains more number of carbons.

The longest chain has seven carbon atoms. By referring the above table, deduce the name as heptane for parent chain.
