Which consequence is likely should degenerate nickel d-orbitals become destabilized?

A)Lower catalytic efficiency results
B)Increased metallic lattice disorder
C)Spin crossover becomes inevitable
D)Reduced interatomic electron tunneling

💡 Explanation

Catalytic efficiency decreases because the destabilization alters electron density and reactivity via the Jahn-Teller Effect. Therefore, optimal orbital interactions reduce the substrate binding, rather than changes to lattice or causing crossover; that requires spin multiplicity.
