Hi, in this question we are given with three coordination compounds and we are asked to find out the charge on the central metal ion and also we need to find out the coordination number.
00:10
If we talk about the coordination number which we can write as cn, we can say that it is total number of coordinate bonds or sigma bond between metal and ligands.
00:39
Here we can say that h2o is a nickel is a metal and if we talk about this complex nih2o6cl2 we can say that it is cationic complex.
00:59
Since cl2 is electronegative it is having a negative charge and it is acting as anion as one cl is having minus one charge we are having two cl2 therefore the complex we will be having is nih2o6cl2+.
01:16
We will be having positive charge on the complex.
01:20
Now we need to find out the charge on metal ion first let us consider the charge on metal nickel bx.
01:28
H2o is a monodentate ligand and it is neutral ligand it means it will not contribute any charge to this ligand therefore we can write plus six into zero equals to overall charge on complex that is plus two hence we can say that the x will be equal to plus two hence we can say the nickel which is a central metal is having plus two charge.
01:53
Now if we talk about the coordination number then we can say that since h2o is a monodentate ligand it will form one sigma bond with nickel and we are having six h2o therefore the coordination number will be six in this case.

Now if we talk about the second complex we are having cren3clo43 we can say that this is anionic part and this is the complex part which will be cationic in nature...
