Chapter 17, Problem 17.39AP

Interpretation Introduction

(a)

Interpretation:

A curved-arrow mechanism for the isomerization of isopentenyl pyrophosphate into dimethylallyl pyrophosphate in the presence of acid $\left(\text{AH}\right)$ and base $\left({\text{A}}^{-}\right)$ is to be stated.

Concept introduction:

The curved-arrow notation is used to show the transfer of electrons from one atom to another. The curved arrow has two barbs (head and tail) which represent the direction of electron flow. The species which accepts proton from another species are termed as Brønsted base. On the other hand, the species which donates proton to another species are known as Brønsted acid.

Interpretation Introduction

(b)

Interpretation:

A curved-arrow mechanism for the transformation of geranyl pyrophosphate into linalool in the presence of acid $\left(\text{AH}\right)$ and base $\left({\text{A}}^{-}\right)$ is to be stated.

Interpretation Introduction

(c)

Interpretation:

A curved-arrow mechanism for the conversion of compound A into compound B in the presence of ${\text{H}}_{\text{2}}\text{O}$ and ${\text{H}}_3{\text{O}}^{+}$ is to be stated.
