Which of the following statements are true according to postulates of ...
Explanation:
Primary Valency:
- According to Werner's theory, primary valency is non-directional in nature. It refers to the oxidation state or the charge of the central metal ion.
- Primary valency is satisfied by negative ions or neutral molecules that coordinate with the central metal ion through ionic or electrostatic bonds.
- The directionality of primary valency is not relevant as it is mainly concerned with the charge of the metal ion.
Secondary Valency:
- On the other hand, secondary valency in Werner's theory is directional in nature.
- It refers to the number of atoms or groups directly attached to the central metal ion through coordinate covalent bonds.
- The coordination number, which is determined by the number of ligands surrounding the central metal ion, is a manifestation of the directional nature of secondary valency.
Conclusion:
- Therefore, the statement that secondary valency is directional in nature is consistent with Werner's theory, while the other statements regarding oxidation state, primary valency, and coordination number do not accurately reflect the directional or non-directional nature of these concepts in the context of Werner's coordination theory.

Which of the following statements are true according to postulates of ...
The secondary valancies are always directed towards fixed position in space and this cause definite geometry of the coordinate compound.
If a metal ion has 6 secondary valencies, these are arranged octahedrally around the central metal ion. If the metal ion has 4 secondary valencies, these are arranged in either tetrahedral or square planar arrangement around the central metal ion. Therefore, Secondary valency is Directional in nature.
Primary valency is non-directional on the other hand as Primary valencies are those which a metal normally exhibit in the formation of its simple salts.
The primary valencies indicate the oxidation state of the central metal atom while the secondary valency indicate about the co-ordination number of the metal atom.
