1 Practice Problems: Transition Elements and Coordination Chemistry 1. Complete the valence level orbital notation for the following monatomic ions. KEY CHEM 1B a) Ag + b) Co 3+ 4d 5s 3d 4s c) Fe 3+ d) Cr 3+ 3d 4s 3d 4s 2. For each of the following complexes, determine the number of ligands and the coordination number and oxidation number of the central metal. [Mn(EDTA)] 2 # Ligands Coordination # Oxidation # [Co(en) 2 (NH 3 )CN] 2+ Pt(NH 3 ) 2 Cl Give the ligand name for each of the following ligands. Donor atom(s) are written in bold. The bottom three in the third column are common abbreviations rather than formulas. H 2 O aqua 2 C 2 O 4 oxalato CN cyano F fluoro NH 3 ammine SCN thiocyanato Cl chloro NO 2 nitro NCS isothiocyanato Br bromo ONO nitrito en ethylenediamine I iodo OH hydroxo gly glycinato CO 3 2 carbonato CO carbonyl EDTA 4 ethylenediaminetetraacetato 4. Circle the ligands above that would require the use of the bis-, tris-, or tetrakis- numeric prefixes in the naming of the complex. Explain why below: Bis-, tris-, tetrakis-, pentakis-, etc. are used with parentheses around the ligand name when the name of the ligand already contains a common numeric prefix (mono-, di-, tri-, etc.), like in ethylenediamine and ethylenediaminetetraacetate. They are also used if the ligand is polydentate, which applies to all four of the circled ligands. Note: Since EDTA 4 is a hexadentate ligand, it is unlikely that more than one will complex the same metal center, making the use of these prefixes less likely for EDTA 4.
2 5. Name the following complex cations, neutral complexes, and complex anions. ethylenediaminetetraacetato- [Cr(H 2 O) 5 Cl] 2+ pentaaquachlorochromium(iii) ion [Fe(EDTA)] ferrate(iii) ion bis(ethylenediamine)dithiocyanatoplatinum(iv) [Pt(en) 2 (SCN) 2 ] 2+ ion [Co(CO 3 ) 3 ] 3 tricarbonatocobaltate(iii) ion diamminebis(oxalato)chromate(iii) [Co(NH 3 ) 5 (NO 2 )] 2+ pentaamminenitrocobalt(iii) ion [Cr(NH 3 ) 2 (C 2 O 4 ) 2 ] ion [Co(en) 3 ] 3+ tris(ethylenediamine)cobalt(iii) ion [Co(NCS) 4 ] 2 tetraisothiocyanatocobaltate(ii) ion Ni(CO) 4 tetracarbonylnickel(0) [Fe(CN) 6 ] 4 hexacyanoferrate(ii) ion 6. Name the following coordination compounds. [Co(NH 3 ) 5 (ONO)]SO 4 pentaamminenitritocobalt(iii) sulfate [Ag(NH 3 ) 2 ][Ag(CN) 2 ] diamminesilver(i) dicyanoargentate(i) tetraamminedibromocobalt(iii) [Co(NH 3 ) 4 Br 2 ]Br bromide K 3 [Fe(C 2 O 4 ) 3 ] potassium tris(oxalato)ferrate(iii) 7. Matching: Match the descriptions below with the letter of a type of isomer on the left. Each letter can be used more than once or not at all. A = Structural Isomers B = Coordination Isomers C = Linkage Isomers D = Stereoisomers E = Geometric Isomers F = Optical Isomers A general category for isomers with different bonds D general category for isomers with the same bonds arranged in different locations F isomers with chiral centers E cis- and trans- isomers F isomers that rotate plane polarized light C isomers that have functional groups bonded through different atoms B isomers that have the same atoms bonded, but bonded in a different way E isomers that occur as the result of rigid bonds 8. Draw condensed structures for 2-propanol, 2-butanol, and 2-butanone. Mark any chiral carbons with an asterisk. OH CH 3 CHCH 3 2-propanol OH CH 3 CHCH 2 CH 3 * 2-butanol O CH 3 CCH 2 CH 3 2-butanone
