Chapter 10.6, Problem 13P

Interpretation Introduction

Interpretation:

The synthesis of $\text{trans-2-heptene}$ from $\text{propyne}$ and any necessary organic or inorganic reagents is to be suggested.

Concept Introduction:

>

The conjugate base of alkyne acts as a good nucleophile, on reaction with primary alkyl halide and undergoesa substitution reaction.

>

The alkyne on hydrogenation by a group 1 metal (lithium, sodium, or potassium) in liquid ammoniaundergoestrans addition of ${\text{H}}_{\text{2}}$ and yields trans alkene.
