Chapter 16, Problem 16.1P

Interpretation Introduction

(a)

Interpretation: The given diene is to be classified as isolated or conjugated.

Concept introduction: Diene is a hydrocarbon that contains two $\text{C}=\text{C}$ double bonds in a compound.

Conjugated diene consists of two double bonds that are separated by a single bond, whereas isolated diene also consists of two double bond but they are separated by two more carbon atoms.

The example that shows the basic difference between conjugated diene and isolated diene is shown below.

Figure 1

Answer to Problem 16.1P

The given diene is a conjugated diene.

Explanation of Solution

Diene is a hydrocarbon that contains two $\text{C}=\text{C}$ double bonds in a compound.

Conjugated diene consists of two double bonds that are separated by a single bond, whereas isolated diene also consists of two double bond but they are separated by two more carbon atoms.

The given diene is shown below.

Figure 2

In the given diene, two double bonds are separated by a single bond. Thus, the given diene is a conjugated diene.

Conclusion

The given diene is a conjugated diene.

Answer to Problem 16.1P

The given diene is an isolated diene.

Explanation of Solution

Diene is a hydrocarbon that contains two $\text{C}=\text{C}$ double bonds in a compound.

Conjugated diene consists of two double bonds that are separated by a single bond, whereas isolated diene also consists of two double bond but they are separated by two more carbon atoms.

The given diene is shown below.

Figure 3

In the given diene, two double bonds are separated by a two sigma bonds. Thus, the given diene is an isolated diene.

Conclusion

The given diene is an isolated diene.

Answer to Problem 16.1P

The given diene is an isolated diene.

Explanation of Solution

Diene is a hydrocarbon that contains two $\text{C}=\text{C}$ double bonds in a compound.

Conjugated diene consists of two double bonds that are separated by a single bond, whereas isolated diene also consists of two double bond but they are separated by two more carbon atoms.

The given diene is shown below.

Figure 5

In the given diene, two double bonds are separated by more than single bond. Thus, the given diene is an isolated diene.

Conclusion

The given diene is an isolated diene.
