  1. Question 1

    Q1. In a reaction involving transition metals, which feature of d-orbitals facilitates catalytic activity?

    • A) Their ability to hold unpaired electrons
    • B) Their low ionization energy compared to s-orbitals
    • C) Their directional shape enabling specific ligand interactions
    • D) Their higher capacity for electron shielding

    Answer: Their directional shape enabling specific ligand interactions

    Explanation: D-orbital directional geometry allows precise ligand binding. Ionization energy and shielding are not primary factors in catalytic site orientation.
