Bis,tris, etc

[Kavee Dodampahala 4E]

When do we use the prefixes bis, tris, tetrakis, pentakis, etc?

[Benjamin Feng 1B]

You use bis and tris when the ligand already has a bi or prefix in front of it. For example, you would say bisethylenediammine as en already has a "di" in it. You also use bis and tris when the ligand is polydentate like EDTA and oxalate.

[Osvaldo SanchezF -1H]

The book on page 723 explains with detail when to use it but the simple matter of it, it that you use it when there is already prefix on the molecule name such as Di converts to Bi and etc, but I would take a glance at the reference number I gave you.

[Natalie Benitez 1E]

When exactly do we use bis, cis, tris, etc.? How are they any different from using the other prefixes such as di, tri, etc.?

[Ruth Glauber 1C]

I think you use it when the ligand already has a bi or prefix.

[Angela Patel 2J]

Do you use them just when the name starts with bi or di or is it just when it has bi, di, etc anywhere in the name?

[Arianna Perea 3H]

how do you know when to use bis and not di?
