← ScienceWhich outcome occurs when a sterically bulky ligand hinders access to a metal's d-orbitals in a catalytic complex?
A)Reduced catalytic activity occurs✓
B)Increased complex water solubility
C)Faster ligand exchange observed
D)Enhanced oxidative stability occurs
💡 Explanation
Reduced catalytic activity occurs because steric hindrance from large ligands inhibits substrate binding via occupied d-orbitals, therefore decreasing reaction rates, rather than increasing solubility or stability which require different interactions.
