← ScienceWhich outcome results when a ruthenium catalyst degrades?
A)Stereoselectivity diminishes significantly during synthesis✓
B)Reaction kinetics becomes thermodynamically downhill
C)Regioselectivity increases catalytic isomerization
D)Turnover number directly enhances enzymatic process
💡 Explanation
When the catalyst degrades due, *d-orbital splitting* changes which loses stabilization and chiral induction properties; therefore, less of the preferred enantiomer forms, rather than accelerated, reversed, or enhanced enzymatic turnover because catalytic enantioselectivity is most impacted by d-orbital configuration.
