- only from the primary valence in space
- number and position of the primary valences in space
- number and position of the secondary valences in space
- only from the position of secondary valence in space

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Werner's theory was used to describe the structure and formation of complex compounds or coordination compounds. According to this theory the primary valency gives the oxidation number and the secondary valency gives the coordination number. Also, the geometry of the complex is determined by number and position of secondary valences in space as the ligand satisfying secondary valences are always directed towards fixed position in space

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
