Which of the following postulates of Werner theory is incorrect?
- A In coordination compounds metals show two types of linkages (valences) - primary and secondary.
- B The primary valences are normally ionisable and are satisfied by negative ions.
- C The secondary valence is equal to the oxidation number of metal and is fixed for a metal.
- D The ions/groups bound by the secondary linkages to the metal have characteristic spatial arrangements corresponding to different coordination numbers.
Answer & Solution
Correct Answer
(C) The secondary valence is equal to the oxidation number of metal and is fixed for a metal.
