Question

How would you account for the following: Transition metals form complex compounds.

Account for the following:

Transition metals form a large number of complexes.

Account for the following:

Transition metals form large number of complex compounds.

Give reasons for the following:

Transition elements form complex compounds.

Answer 1

The transition elements form complexes because they are able to accept pairs of electrons from donor molecules or ions to form dative covalent bonds. This happens because they have vacant orbitals of suitable energy which can accept the non-bonding pairs from the ligands.

Answer 2

The transition elements form complexes because of the following reasons:

1. Comparatively smaller size of their metal ions.
2. Their high ionic charges.
3. Availability of vacant d-orbitals so that these orbitals can accept lone pairs of electrons donated by the ligands.
