What is the name of the following compounds;
Hg2(BrO2)2
Au(OCN)3
AuSCN
Ni3(AsO4)2
Thank you
The names of the compounds you mentioned are as follows:
1. Hg2(BrO2)2 - Mercury(I) bromate
2. Au(OCN)3 - Gold(I) cyanate
3. AuSCN - Gold(I) thiocyanate
4. Ni3(AsO4)2 - Nickel(II) arsenate
To name the compounds you provided, we need to follow some naming rules. The rules differ depending on whether the compound is an ionic compound or a coordination compound.
1. Hg2(BrO2)2:
This compound is an ionic compound. To name it, we first identify the individual ions involved.
The Hg2 ion is called "mercury(I)" ion, and the (BrO2) ion is called "bromate" ion.
Therefore, the name of the compound is Mercury(I) bromate.
2. Au(OCN)3:
This compound is a coordination compound. Coordination compounds consist of a central metal atom or ion surrounded by ligands. In this case, Au is the central atom, and OCN acts as the ligand.
To name the compound, we first identify the ligands and their charges. OCN is a negatively charged ligand called "cyanate."
Since there are three cyanate ligands, the name of the compound is Tris(cyanato)gold(III).
3. AuSCN:
This compound is also a coordination compound. Au is the central atom, and SCN acts as the ligand.
To name the compound, we identify the ligands and their charges. SCN is called "thiocyanate" and is negatively charged.
The name of the compound is Gold(I) thiocyanate.
4. Ni3(AsO4)2:
This compound is an ionic compound. We identify the individual ions involved.
The Ni ion is Nickel(II), and the (AsO4) ion is called "arsenate."
Since there are two arsenate ions, the name of the compound is Nickel(II) arsenate.
Remember, it's essential to properly identify the ions and ligands in a compound before applying the naming rules.
Name the metal first, give it a roman numeral if it has more than one oxidation state, then name the anion. For example, AuSCN is gold(I) thiocyanate. I assume this assignment is to familiarize you with the names of polyatomic anions. Here is a fairly complete table with formulas and names.
