Chapter 10, Problem 37PP

(a)

Interpretation Introduction

Interpretation:

The different alkene, alkane products formed for each given substrates when treated with a different reducing reagents are needed to be find out.

Concept Introduction:

Hydrogenation reaction: The hydrogenation is a reduction reaction which results in an addition of hydrogen. Several organic compounds is hydrogenated, it becomes more saturated.

Metal reduction reaction: The alkenes can be reduced to alkanes with H₂ in the presence of metal catalyst (Pt). The two new C-H σ bonds are formed simultaneously from H atoms absorbed into the metal surface. This type of reaction stereospecific giving only the cis (syn) addition product.

Linder’s catalyst: The alkyne reduced to alkenes to give the cis (Z) alkene.

Metal and ammonia reaction: The alkyne involves sodium $\left(\text{Na}\right){\text{/NH}}_{\text{3}}$. This end up reducing to alkyne to give the trans (E) alkene.
