Name: _________________________________________ Date:____________________________ Homework 5 Insert space or answer questions on a separate sheet of paper 1.) Give systematic names for the following: a. [Ni(H2O)6]Cl2 b. [Cr(en)3](ClO4)3 c. K4[Mn(CN)6] d. [V(H2O)6]SO4 e. [Pt(NH3)2Cl2F2] 2.) Write the formulas for the following compounds: a. Tetraamminezinc sulfate b. Pentaamminechlorochromium(III) chloride c. Dibromobis(ethylenediamine)cobalt(III) sulfate 3.) Draw the indicated isomers for the following compounds: a. Geometric: [Pt(CH3NH2)2Br2] the N is attached to platinum: identify which is cis/trans b. Linkage: [Cr(NH3)5(NO2)]+2 c. Coordination isomers: [Pt(CH3NH2)3Br]Cl and [Pt(CH3NH2)3Cl]Br 4.) Draw the splitting diagram for an octahedral complex Draw the splitting diagram for a tetrahedral complex Draw the splitting diagram for a square planar complex Be SURE to identify which d orbitals are located where!! 5.) What is the distinction between a weak field and a strong field ligand? What does it mean for electrons filling the d orbitals? Give an example of a weak field ligand. Give an example of a strong field ligand 6.) Draw orbital energy splitting diagrams and use the ligand strength series to show how the electrons would fill the d orbitals (orbital occupancy) for each of the following: Are the species high spin or low spin complexes: Hint: the ligand tells you if the ∆ is large or small. The d orbitals electrons come from the metal ION. a. [Cr(CN)6]-4 b. [Rh(CO)6]+3 c. [Fe(Cl)6]-4 d. [Fe(CO)6]+2 7.) Consider the series Cl2, Br2, and I2. What trend is observed in bond strength? Considering the sizes of the atoms, what trend would you predict for bond length?
