Chapter 9.7, Problem 8P

Interpretation Introduction

Interpretation:

Using the given compounds and any other necessary organic and inorganic reagents, the preparation of propyne by writing appropriate series of equation is to be shown.

Concept Introduction:

>

Alkynes can be prepared by alkylation of acetylene.

>

Double dehydrohalogenation of either vicinal or geminaldihalides also produces alkynes.

>

Vicinal dihalides are prepared by addition of halogens to alkenes.

>

Alkenes in turn can be prepared from alcohols by acid catalyzed dehydration.

>

Alkenes can also be prepared by elimination reactions of alkyl halides.
