Chapter 7, Problem 25PP

Interpretation Introduction

Interpretation:

The reactions for the synthesis routes for $2-\text{methylhexane}$ are to be written.

Concept introduction:

The Lindlar’s catalyst consists of hydrogen in the presence of metal catalyst used to produce alkanes from alkenes and alkynes.

${\text{NaNH}}_2$ abstracts the most acidic proton from the reactant molecule in the reaction medium.

Reduction is a process in which hydrogen atoms are added to a compound.

Usual reagents used in reduction process include ${\text{H}}_2/\text{Pt}/\text{pressure}$ or ${\text{H}}_2/\text{Ni}/\text{pressure}$.

The addition of hydrogen to double or triple bond is a hydrogenation reaction.

Hydrogenation of alkenes or alkynes is an addition reaction, which is done in the presence of reducing agents, such as ${\text{H}}_2/Ni$.

The number of hydrogen molecules reacted is equal to the number of double bond present.
