MCQ
$D-$block elements form complexes because they have:
- AVacant orbitals.
- BSmall sizes.
- CHigher nuclear charge.
- ✓All of the above.
✓
Answer
Correct option: D.
All of the above.
Transition metals has incompletely filled $d$ orbital. They have vacant orbitals to accept coordination bond. Complex compounbs are those in which the metal ion bind a number of anions or neutral molecules giving complex species with characteristics properties. The transition metals form a large no. of complex compounds.
This is due to the comparatively smaller size of the metal ions,their high ionic charges and the availability of $d$ orbitals for bond formation.
