Question

According to Werner’s theory of coordination compounds:

• A. Primary valences are ionisable.
• B. Secondary valences are ionisable.
• C. Both primary and secondary valences are non-ionisable.
• D. Both primary and secondary valences are ionisable.

Hint:

Werner’s theory distinguishes between primary valences (oxidation state) and secondary valences (coordination number), which are essential to understanding coordination compounds.

Answer 1

The Correct Option is A

Werner's theory posits that primary valences are ionisable and align with the central metal ion's oxidation state in a coordination compound. In contrast, secondary valences are non-ionisable and reflect the coordination number, signifying the quantity of ligands bonded to the metal ion. Therefore, primary valences are ionisable, while secondary valences are not.
