Question

1. Name following coordination complexes. (a) K[PdCL 6) Co(H2O) (NH). 6) M(NH) (En) ([C-CL:(NH4Cl2 2. State the coordination number and oxidation state of the following catalysts. @) [P!(CO).PPh] (b) [Ni(C1) [lr(CI)(CO)En(PPhy)]" (d) Liz[AuC)

Apologies, this is inorganic chemistry, couldn't find a subject tab for this. Thank you in advance

just need assistance with both questions

Answer 1

IUPAC rules for naming complex compounds:

1. For ionic complexes, always name the cation first.

2. In complex ion, name the ligands first and then the central atom.

3. If more than one ligand present, use di, tri, tetra,..... suffix.

4. For polydentate ligands, use bis, tris, tetrakis... as suffix.

5. If different ligands are present, follow alphabetical order.

6. For neutral and cationic complex ions, central metal name is written as it is.

7. For anionic complexes, the central metal atom name ends with -ate.

8. Oxidation number of central atom must be shown in Roman numbers after the metal name.

The IUPAC names for the given complex compounds are as follows:

(a) K, [PdC1, ]- Potassium tetrachloropalladate(II) . - Tetraamminediaquacobalt(II) cation Tetraammineethylenediamminemanganese(II) cation Tetraamminedichlorochromium(IV) chloride
