Question

Which of the following factors favour the formation of complexes by d-block elements?

• A. small size
• B. High nuclear charge
• C. Presence of low energy vacant orbitals to accept lone pair of electrons donated by ligands
• D. All of the above

Answer 1

The correct option is D All of the above

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