QUESTION 5 (a) The complex ion (Co(CN)o] has absorbed wavelength at 310 nm but (CoFolion at 700 nm. 0 Which one of the ligands, CN or F. would produce a larger crystal field splitting, A and why? (2 marks) () Determine whether (Co(CN).] and [CoFo] each are high spin or low spin complex (1 mark) [Co(CN)) = [CoFil" = (II) Using crystal field theory, draw a completely labeled diagram of the splitting of the a orbitals in each complex ion. [Co(CN).J* (2 marks) [CoFo] (2 marks) (iv) How many unpaired electrons are there in each complex ion and state whether they are diamagnetic or paramagnetic. (4 marks) [Co(CN).] = [CoFe] = (b) Two test tubes each contain a different chromium complex ion that is violet and yellow. Consider the complex ions [Cr(H20).] and [Cr(NH3)]** Predict the color of each solution. (2 marks) [Cr(H2O).P= [Co(NH3) (ii) Explain. (2 marks) =
