Here are the essential concepts you must grasp in order to answer the question correctly.
Chirality in Catalysts
Chirality refers to the geometric property where a molecule is not superimposable on its mirror image, much like left and right hands. In catalysis, chiral catalysts can induce stereoselectivity, leading to the preferential formation of one enantiomer over another in a chemical reaction. This is crucial in synthesizing compounds with specific desired properties, such as pharmaceuticals.

Enantioselective Hydrogenation
Enantioselective hydrogenation is a process where a chiral catalyst is used to selectively hydrogenate one enantiomer of an unsaturated compound over the other. This reaction is important in producing enantiomerically pure compounds, which are often required in drug synthesis. The choice of catalyst, such as (R)-BINAP or (S)-BINAP, determines the stereochemistry of the product.

Role of BINAP in Catalysis
BINAP (2,2'-bis(diphenylphosphino)-1,1'-binaphthyl) is a chiral ligand used in asymmetric catalysis. It forms complexes with metals like Rhodium, which can then catalyze reactions with high enantioselectivity. The (R) or (S) configuration of BINAP influences the spatial arrangement of the reactants, thus determining the stereochemistry of the hydrogenation product.
