Coordination Chemistry(Quiz-4) 1 / 5 According to IUPAC nomenclature, sodium nitroprusside is named as: Sodium nitroferricyanide Sodium nitroferrocyanide Sodium pentacyano nitrosylferrate (II) Sodium pentacyano nitrosylferrate (III) According to IUPAC nomenclature, the compound sodium nitroprusside is named as Sodium pentacyano nitrosylferrate (III). This name indicates the composition and oxidation state of the compound. "Sodium" refers to the presence of sodium ions, "pentacyano" indicates the presence of five cyanide ligands, "nitrosyl" indicates the presence of a nitrosyl ligand, and "ferrate (III)" indicates the oxidation state of iron in the compound. 2 / 5 Hybridisation and shape of K3[Co(CO3)3] is: D2sp3and Octahedral Sp3d2 and Octahedral Dsp2 and square planar Sp3 and tetrahedral The hybridization and shape of K3[Co(CO3)3] is sp3d2 and Octahedral. In this compound, the central cobalt atom is bonded to six ligands, three of which are carbonate ions (CO3) and three are potassium ions (K). The cobalt atom undergoes hybridization to form six hybrid orbitals, consisting of one s orbital, three p orbitals, and two d orbitals. These hybrid orbitals then overlap with the ligand orbitals to form six sigma bonds, resulting in an octahedral shape. 3 / 5 Total number of possible isomers for the complex compound [CuII(NH3)4][PtIICl4] are: 3 4 5 6 The complex compound [CuII(NH3)4][PtIICl4] consists of two parts: the copper complex [CuII(NH3)4] and the platinum complex [PtIICl4]. The copper complex contains a central copper ion surrounded by four ammonia ligands, while the platinum complex contains a central platinum ion surrounded by four chloride ligands. The number of possible isomers for each complex can be determined using the coordination number and geometries of the ligands. For the copper complex, the coordination number is 4 and the ligands are all the same, resulting in only one possible isomer. For the platinum complex, the coordination number is also 4, but the ligands are different, allowing for different possible arrangements. Therefore, the total number of possible isomers for the complex compound is 1 * number of isomers for the platinum complex, which is 4. 4 / 5 Square planar complexes of the type MABXL (where A, B, X and L are unidentates) show: Two cis and one trans isomer Two trans and one cis isomer Two cis and two trans isomer One cis and one trans isomer Square planar complexes have a square planar geometry, meaning that there are four ligands arranged around the central metal atom in a flat plane. In this case, the complex is MABXL, where A, B, X, and L are unidentate ligands. The two cis isomers refer to the arrangement of the ligands where two of them are located on the same side of the square plane, while the other two are on the opposite side. The trans isomer refers to the arrangement where two ligands are located opposite to each other across the square plane. Therefore, the correct answer is two cis and one trans isomer. 5 / 5 In spectrochemical series, chlorine is above water i.e., Cl > H2O, this is due to: Good π-acceptor properties of Cl Strong σ-donor and good π-acceptor properties of Cl Good π-donor properties of Cl Larger size of Cl than H2O The correct answer is "Good π-donor properties of Cl." In the spectrochemical series, the position of a ligand is determined by its ability to donate electron density to the metal center. Chlorine has good π-donor properties, meaning it can donate electron density to the metal through its p-orbitals. This makes it a strong ligand and places it above water in the spectrochemical series. Your score isThe average score is 0% 0% Restart quiz
