Explanation
[CuII(NH3)4[PtIICl4] shows [Cu(NH3)3 Cl][PtCl3NH3],[CuNH3Cl3][Pt(NH3)3Cl] and [CuCl4][Pt(NH3)4] other isomers. The isomer [Cu(NH3)2 Cl2][Pt(NH3)2Cl2] does not exist due to both parts being neutral.
2CuSO4 + 10KCN →2K3[Cu(CN)4] + (CN)2 + 2K2SO4
Metal atom in the complex part does not give its test.
Each NH3 molecule has three covalent bonds and total covalent bonds are 6 × 3 = 18
IUPAC name is potassium trioxalatoiridate (III).
At. No. of Fe = 26, oxidation state of Fe in the complex [Fe(CN)6]3- is + 3. Therefore, EAN = 26 – 3 + 12 = 35.
NH3 cannot show linkage isomerism as it doesnot contain two donor atoms.
[Cr(NH3)5(NO2)]Cl2 shows linkage isomerism. It also shows ionization isomerism.
Sodium nitroprusside Na2[Fe(CN)5NO] is named as sodium pentacyanonitrosylferrate (III). In this compound.NO is present as NO+ and Fe has +2 charges.On the basis of this, the actual name should be sodium pentacyanonitrosoniumferrate (II)
[CoF6]3- contains Co3+ = d6 system with four unpaired electrons.
(CH3)4 Sn is a σ − bonded organometallic compound.
[Pt(en)2Cl2] shows cis-trans isomerism and cis form also shows optical activity.
Zinc (Zn2+) will form complex with aq. NaOH and ammonia as Na2[Zn(OH)4] and [Zn(NH3)4 Cl2] respectively. But Aluminium (i.e. Al3+) will form complex only with NaOH. i.e. Na[Al(OH)4]
A spectrochenical series is a list of ligands ordered on ligand strength and a list of metal ions based on oxidation number, group and its identity.
Hence the order is, NH3<en<CN- <CO
