Chapter 17, Problem 17.47AP

Interpretation Introduction

(a)

Interpretation:

The curved-arrow mechanism for the reaction of $\text{2-hexyne}$ with strong base $\left({}^{-}{\text{NHCH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{NH}}_{\text{2}}\right)$ is to be predicted. The explanation for the fact that the corresponding reaction is irreversible reaction is to be stated.

Concept introduction:

The isomerization process of converting internal alkynes into terminal alkynes is known as acetylene zipper reaction. The acetylene zipper reaction required a strong base. A diamine ion is used in the reaction to transfer proton from one carbon atom to another carbon atom.

Interpretation Introduction

(b)

Interpretation:

The product of reaction of $\text{3-methyl-4-octyne}$ with strong base $\left({}^{-}{\text{NHCH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{NH}}_{\text{2}}\right)$ is to be predicted.
