Chapter 12, Problem 49P

Interpretation Introduction

(a)

Interpretation:

The structure of $3-\text{ethylhexane}$ should be drawn.

Concept Introduction:

To draw the structure from IUPAC name of any compound, some rules need to be followed.

The rules are −

1. Draw the longest continuous carbon chain of the molecule.
2. Number the carbons in the longest carbon chain.
3. Add the substituents in the respected positions. Just like for methyl, $-{\text{CH}}_{\text{3}}$ ; for ethyl, $-{\text{CH}}_{\text{2}}{\text{CH}}_{\text{3}}/-{\text{C}}_{\text{2}}{\text{H}}_{\text{5}}$ .

Interpretation Introduction

(b)

Interpretation:

The structure of $3-\text{ethyl}-3-\text{methyloctane}$ should be drawn.

Concept Introduction:

To draw the structure from IUPAC name of any compound, some rules need to be followed.

1. Draw the longest continuous carbon chain of the molecule.
2. Number the carbons in the longest carbon chain.
3. Add the substituents in the respected positions. Just like for methyl, $-{\text{CH}}_{\text{3}}$ ; for ethyl, $-{\text{CH}}_{\text{2}}{\text{CH}}_{\text{3}}/-{\text{C}}_{\text{2}}{\text{H}}_{\text{5}}$ .

Interpretation Introduction

(c)

Interpretation:

The structure of $2,3,4,5-\text{tetramethyldecane}$ should be drawn.

Concept Introduction:

To draw the structure from IUPAC name of any compound, some rules need to be followed.

Interpretation Introduction

(d)

Interpretation:

The structure of $\text{cyclononane}$ should be drawn.

Concept Introduction:

To draw the structure from IUPAC name of any compound, some rules need to be followed.

The rules are −

1. Draw the longest continuous carbon chain of the molecule.
2. Number the carbons in the longest carbon chain.
3. Add the substituents in the respected positions. Just like for methyl, $-{\text{CH}}_{\text{3}}$ ; for ethyl, $-{\text{CH}}_{\text{2}}{\text{CH}}_{\text{3}}$ .
