(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)
