← ScienceAn organometallic catalyst facilitates a reaction; which outcome risks reduced turnover?
A)Orbital symmetry mismatch impeding substrate binding✓
B)Increased steric bulk enhancing reagent accessibility
C)Ligand dissociation improving catalytic activity
D)Metal reduction potential favoring product release
💡 Explanation
A symmetry mismatch slows reactions because the concerted interaction via Frontier Molecular Orbital Theory requires compatible phases to form new bonding orbitals; therefore, catalytic activity decreases, rather than activity improving with steric or reduction effects.
