Chapter 12, Problem 12.3P

Interpretation Introduction

(a)

Interpretation: All alkenes that react with one equivalent of ${\text{H}}_{\text{2}}$ in the presence of a palladium catalyst to form the given alkane are to be stated.

Concept introduction: The addition of ${\text{H}}_{\text{2}}$ in presence of metal catalyst is known as catalytic hydrogenation. This is a syn addition. Alkene is reduced to alkane. In this reaction, weak pi bond of alkene and sigma bond between ${\text{H}}_{\text{2}}$ is broken and two $\text{C}-\text{H}$ bonds are formed.
