What is the coordination number of platinum in the complex ion cis-diamminedichloroplatinum(ii)?

The coordination number of platinum is 4.

Explanation:

Coordination number is defined as the number of ligands that are attached to the central metal atom in a complex ion.

The complex given to us is: cis-diamminedichloroplatinum(ii)

The chemical formula for this complex is

In this complex, two ammine atoms are attached to platinum and two chlorine atoms are attached to platinum. This complex is also named as Cisplatin.

The structure of this complex is given in the image attached.

Hence, the coordination number of platinum is 4.

the answer is either b or c

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
