Chapter 17, Problem 17.37QP

Interpretation Introduction

Interpretation:

Using the line formulas for cis-5,8,11,14,17-eicosapentaenoic acid, the hydrogenation equation should be written.

Concept Introduction:

Platinum reduction reaction: The alkenes or alkynes can be reduced to completely saturated alkanes with $H_2$ in the presence of metal catalyst $\left(Pt\right)$. The two new $C-H\sigma$ bonds are formed simultaneously from H atoms absorbed into the metal surface.

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

Reduction reaction: The alkenes or alkynes can be reduced to alkanes with in the presence of metal catalyst. The new bonds are formed simultaneously from atoms absorbed into the metal surface.
