Identify the following terms in the complex [K 4 Fe (CN) 6] (i) Cation (ii) Anion (iii) ligands (iv) central metal ion (v) Oxidation state of metal (vi) IUPAC name Answer: Question 6. 22 - A transition metal coordination compound absorbs... Ch. 22 - Which of the following complex ions is (are)... Ch. This is based on the ratio of compounds bonded to the metal ion. Answer/Explanation. View solution Predict the number of unpaired electrons in a tetrahedral d 6 ion and in square planar d 7 ion. Answer: Explaination: (b) and (c) are correct statement ∆ t = $$\frac{4}{9}$$ ∆ 0 Value of C F S E depends upon nature of ligand and a spectrochemical series has been made experimentally, for tetrahedral complexes, is about 4 / 9 times to 0 (C F S E for octahedral complex). This may attributes to the following two reasons. (c) tetrahedral complexes have smaller crystal field splitting than octahedral complexes. Ch. tetrahedral. The absorption in the electronic spectrum of [HfOH2)6]3+ is assigned to the Eg ← T2g transition. In tetrahedral complexes none of the ligand is directly facing any orbital so the splitting is found to be small in comparison to octahedral complexes. For a tetrahedral d4 complex, 3 absorptions are expected in its electronic spectrum. Based on crystal field theory explain why Co(III) forms a paramagnetic octahedral complex with weak field ligands whereas it forms a diamagnetic octahedral complex with strong field ligands. Solution: The first three complexes can have cis and trans isomers. What are the respoective central-metal oxidation state, coordination number, and overall charge on the complex ion in Na2[Cr(NH3)2(NCS)4] +2; 6; -2. For the same metal, the same ligands and metal-ligand distances, it can be shown that del.tetra = (4/9) del.oct. Which of the following complexes have a maximum number of unpaired eletrons? none of them. View solution Geometry, hybridisation and magnetic moment of the ions [ N i ( C N ) 4 ] 2 − , [ M n B r 4 ] 2 − and [ F e F 6 ] 4 − respectively are: This energy lies in visible region and i.e., why electronic transition are responsible for colour.
