Question

The coordination number of the central ion may be obtained from:

पर्याय

• The number of ions of opposite charge immediately surrounding the specific ion.

• The number of ionic bonds formed with the surrounding ions.

• The number of pi bonds formed by the ligand donor atoms with the central metal atom/ion.

• The number of sigma bonds formed by the ligand donor atoms with the central metal atom/ion.

Answer 1

The number of sigma bonds formed by the ligand donor atoms with the central metal atom/ion.

Explanation:

Coordination number of the central metal atom/ion is equal to the number of ligand donor atoms directly bonded to the central metal atom/ion. So it can be determined by the number of sigma bonds formed by the ligands with the central metal atom/ion.
