Q: Which is true about subatomic particles? (2 pts) (e) If [CoI 6] 3-is reduced by one electron to [CoI 6] 4-(which now contains a high spin Co 2+ ion), ligand exchange reactions become much more rapid than those of [CoI 6] 3-. Because Br^- is a weaker field ligand than F^- (G: spectrochemical series) [CoBr6]^3- … Co is in +3 oxidation state in the complex [CoF 6] 3-. Who are the experts?Our certified Educators are real professors, teachers, and scholars who use their academic expertise to tackle your toughest questions. Hence, [CoF 6] 3- is sp 3 d 2 hybridized and it is octahedral in shape. Explain why they display different magneticbehavior. Please explain. Select the correct answer below: In a tetrahedral complex, \(Δ_t\) is relatively small even with strong-field ligands as there are fewer ligands to bond with. Consequently, the six electrons are distributed to each of the orbitals. 3- FeF63– is low spin d5 with no d – d spin allowed transitions. The pairing of these electrons depends on the ligand. ii) If ∆ o > P, it becomes more energetically favourable for the fourth electron to occupy a t 2g orbital with configuration t 2g 4 e g 0. [CoF6]^3- (small F^- ligand) exists and is one of the few high spin cmplxs of Co(III). the number of unpaired electron in the complex ion cof6 3 is - Chemistry - TopperLearning.com | zs9jy2jj ... F- is a weak ligand and therefore will have a high spin state. Because of this, most tetrahedral complexes are high spin. 30. An ion M 2 +, forms the complexes [M (H 2 O) 6 ] 2 +, [M (e n) 3 ] 2 + and [M B r 6 ] 4 −, match the complex with the appropriate colour. Draw the structure of this intermediate. Find solutions for your homework or get textbooks Search a. Next we need to … O True As a result, the fourth electron enters one of the e g orbitals, thereby, exhibiting the electronic configuration t 2g 3 e g 1. Co(III) is 3d^6: high spin: t2g (↑↓) (↑)(↑) (↑)(↑)eg. (d) The reaction of [CoI 6] 3-with F-generates a reactive intermediate. Check 2 Answers 1- FeF63– is high spin d5 should have a single d – d spin allowed transition. (c) Low spin complexes can be paramagnetic. We will be looking at the metal center of these complex ions with respect to the crystal field theory. (b) What type of isomerism is shown by the complex [Co(NH 3) 5 S0 4]Br? I think it's D, but I'm not sure. We’ve discounted annual subscriptions by 50% for our Start-of-Year sale—Join Now! (ii) If Δ0 < P, the configuration will be t2g, eg and it is in the case of weak field ligands and high spin complex will be formed. (a) In an octahedral crystal field, the d electrons on a metal ion occupy the e g set of orbitals before they occupy the t 2g set of orbitals. Find answers to questions asked by student like you. Without doing any calculations, determine which solution in each pair is more basic.a. The hexafluorocobalt(III) cmplx ion is one of only two Co(III) cmplxs that is high spin. c) paramagnetic, with 4 unpaired electrons. b.

Step 3: Determine whether the ligand induces is a strong or weak field spin by looking at the spectrochemical series. For the complex ion [CoF 6] 3- write the hybridization type, magnetic character and spin nature. Median response time is 34 minutes and may be longer for new subjects.

Halides < Oxygen ligands < Nitrogen ligands < CN- ligands. Which is a more likely color for this ion to absorb, red or blue? How many unpaired electrons are there in the high-spin complex ion [CoF6]3−? Since Fluorine is a weak field, it will be a high spin complex. Usually, electrons will move up to the higher energy orbitals rather than pair. Hence, [Ni (CN) 4] 2– is dsp 2 hybridized and it is square planar in shape. Ligands for which ∆ o < P are known as weak field ligands and form high spin complexes. Question: How Many Unpaired Electrons Are There In The High-spin Complex Ion [CoF6]3−?
