(a)

Interpretation Introduction

To determine: The structural formulas of the reagents and the products in the preparation of disiamylborane.

Interpretation: The structural formulas of the reagents and the products in the preparation of disiamylborane are to be shown.

Concept introduction: The synthesis of compound relies upon the type of reactants and reagents that are used during the reactions. The main factors aids in the formation of a product are steric hindrance, stability and feasibility of a reaction.

The reagents perform numerous functions in reactions like proton abstraction, oxidation, reduction, catalysis, and dehydrogenation.

(b)

Interpretation Introduction

To determine: The reason as to why the reaction in part(a) goes only as far as the dialkylborane and ${\text{Sia}}_3\text{B}$ is not formed in the reaction.
