See the 10th example and tell me where I am wrong here, apart from the missed out oxidation state in the end.

the mistake is not mentioning of oxidation state......

Frankly I couldn't care less if the answer were wrong, it seems right to me. If you know the answer, why don't you post it for the benefit of others in the forum??

@ Pritish

I think he wanted to quote the mistake is, not mentioning of oxidation state..

this was only the mistake that he want to tell you may be because he didn't used punctuations well, the sentence is giving some other meaning

@ Pritish you have written chlori instead of chloro( may be this is only the mistake he is telling)

diamminedichloroplatinum dichloroplatinate

am not sure about the oxidation state, so haven't written

@ Nihal please give out the correct answer to this question

Khyati, it's another way of writing the nomenclature when halogen ligands are involved...and it's the newer way. Instead of chloro, it would be chlorido. The oxidation state of the anion complex is easily found. Let Pt's state be x.
x - 2 = -1(Charge on coordination sphere)
=> x = 1.

So the name is tetraaminedichloridoplatinum(III) dichloridoplatinate(I).

Why didn't he give the answer if all I did was miss the oxidation state? lol...bachche aajkal.

Thanks a lot Pritish for the information. :)

@ Pritish, I did this lesson today from Arihant, but they have nowhere mention about the new way of nomenclature of the halogen ligands.

Can you tell what name we have to follow for halogens while naming the complex compounds in JEE?

Khyati ·

@ Nihal, your representation of the complex compound is incorrect.

While write the complex compound we first write the negative ligand, then neutral and then the positive ones.

Correct representation is

[PtCl2(NH3)4 ] [PtCl2]

And the naming done by Pritish is correct

@Khyati : I read about this nomenclature in Pradeep..using halo instead of halido isn't wrong either. Most people find it easier to remember halo. But it's good to know the other way incase it comes in JEE. They are equivalent.
