What factors contribute to the formation of complex compounds by transition metals?

Options

  1. ALarge sizes of the metal ions and low ionic charges
  2. BAvailability of d orbitals for bond formation
  3. CHigh ionic charges and small sizes of the metal ions
  4. DBonding with alkali metals

Correct answer

B. Availability of d orbitals for bond formation

Step-by-step solution

The transition metals form a large number of complex compounds. This is due to the comparatively smaller sizes of the metal ions, their high ionic charges and the availability of d orbitals for bond formation
