Chapter 17, Problem 17.44AP

Interpretation Introduction

(a)

Interpretation:

The reason as to why $1,3-\text{cyclopentadiene}$ is stronger carbon acid than $1,4-\text{pentadiene}$ is to be stated.

Concept introduction:

Diene is a hydrocarbon that contains two 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 bonds but they are separated by two more carbon atoms.

Interpretation Introduction

(b)

Interpretation:

The reason as to why $3-\text{bromo}-1,4-\text{pentadiene}$ undergoes solvolysis easily in protic solvents but $5-\text{bromo}-1,3-\text{cyclopentadiene}$ not is to be stated.

Concept introduction:

Diene is a hydrocarbon that contains two 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 bonds but they are separated by two more carbon atoms.
