Question

primary and secondary valency of [Pt(en)2Cl2]Cl2​

Answer 1

Answer:

The primary valency is the number of negative ions which are equivalent to the charge on the metal ion. The secondary valency is the number of ligands that are attached or coordinated to metal ion.

Answer 2

Answer:

Hence the oxidation state of Pt in the complex is +2. This is the primary valency of platinum, i.e. +2. Hence, the primary and secondary valency of platinum in the given complex is 2,6. There is a second possibility also.
