Chapter 17, Problem 17.38QP

Interpretation Introduction

Interpretation:

Using the line formulas for cis-4,7,10,13,16,19-docosahexaenoic acid, the hydrogenation equation should be written.

Concept Introduction:

Reduction reaction: The alkenes or alkynes can be reduced to completely saturated alkanes with $H_2$ in the presence of metal catalyst $\left(Ni\right)$. 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.
