Chapter 9.5, Problem 12CC

Interpretation Introduction

Interpretation:

The target molecule should be drawn and identified for the given string molecule by using its molecular formula.

Concept Introduction:

Birch reduction: The conjugated alkynes and benzenes in the presence of sodium metal in liquid ammonia and alkyne produced a non-conjugated diene system. The alkyne involves sodium $\left(\text{Na}\right){\text{/NH}}_{\text{3}}$. Further alkyne triple bond end parts reducing to give the trans (E) alkene.

Metal reduction: The alkyne molecules can also be reduced to trans alkenes via an entirely different reaction called dissolving metal $\left({\text{Na/NH}}_{\text{3}}\right)$.
