  1. Question 1

    Q1. Why do reactions involving d-block elements often proceed via inner-sphere electron transfer mechanisms?

    • A) D-orbitals provide direct ligand coordination pathways
    • B) D-block elements have higher ionization energies
    • C) D-orbital electrons have greater shielding effects
    • D) D-orbitals require less energy for excitation

    Answer: D-orbitals provide direct ligand coordination pathways

    Explanation: Coordination complexes enable direct orbital overlap. Ionization energy and shielding are unrelated to transfer mechanism.
