Q49 P - Chemistry: Molecular Nature Of Matter And Change

Question

What geometries are associated with the coordination numbers 2, 4, and 6?

Step-by-Step Solution

Answer

The geometries are given below 

 

Coordination Number                   Geometry

                  2                                    Linear

                  4                                    Square planar or tetrahedral

                  6                                    Octahedral

Step 1: Definition of Coordination Compound

A coordination complex consists of a central atom or ion, which is sometimes metallic and is termed the coordination centre, and a surrounding array of bound molecules or ions, that are successively referred to as ligands or complexing agents.

Step 2: Solve the given statements

Coordination number refers to the number of atoms or donor atoms (groups) attached to the central atom. Certain coordination numbers have molecular geometrics associated with them depending on the number of ligands involved.
