Question 7

Name the following: Fe[AlF₆] A)ironaluminumhexafluoride B)iron(II)hexafluoroaluminum C)iron (III)hexafluoroaluminate D)iron(I)aluminumhexafluoride E)aluminumhexafluoroferrate

Accepted Answer

The Fe in the compound indicates that it is iron. The AlF6 part of the compound suggests that aluminum is bonded to six fluorine atoms, creating an octahedral complex ion. The -ate ending on the compound name suggests that it is a complex ion, and the overall charge of the ion must be -1 to balance the +1 charge on iron. Therefore, iron must be in the +3 oxidation state, making the correct choice iron (III) hexafluoroaluminate.

Accepted Answer

The correct name is hexacarbonyliron(II) dicyanoargentate. The formula indicates an iron (Fe) complex with six (hexa) CO ligands, indicating it is iron(II) in a complex anion with silver (Ag) and two cyanide (CN) ligands, which is correctly named as dicyanoargentate.

Question 13

Choose the electron configuration for Zr²⁺. A)[Kr]5s²4d² B)[Kr]5s² C)[Kr]4d² D)[Ar]4s²3d¹⁰4p⁶ E)[Kr]5s²4d⁴

Accepted Answer

The electron configuration given starts with [Kr], which indicates that the preceding noble gas configuration is being used as a shorthand. Therefore, we can eliminate choices A, B, D, and E, which all include the 5s orbital. Zirconium (Zr) has a ground state configuration of [Kr]4d^25s^2. The sulfur (S) and phosphorus (P) atoms both have ground state configurations of [Ne]3s^23p^4, but in this compound they are both ionized (S1+ and P3-). Since the S has lost one electron, its configuration is now [Ne]3s^23p^3. Similarly, the P has gained three electrons, so its configuration is now [Ne]3s^23p^6. Putting it all together, we get the correct electron configuration of [Kr]4d^2².

Question 14

Determine the chemical formula for the compound diamminetetraaquairon(II)chloride. A)[Fe(NH₃)₂(H₂O)₄Cl] B)[Fe(NH₃)₂][(H₂O)₄Cl] C)[Fe(NH₃)₂(H₂O)₄]Cl₂ D)[Fe(H₂O)₄][(NH₃)₂Cl] E)[Fe(NH₃)₂(H₂O)₄]Cl₃

Accepted Answer

The chemical formula for diamminetetraaquairon(II)chloride is [Fe(NH3)2(H2O)4]Cl2. The formula given in choice C is the correct representation of this compound, with the Fe ion surrounded by two NH3 molecules and four H2O molecules, and the chloride ion as a separate ion. The other choices have incorrect symbols and subscripts, or they have combined the Fe complex and the chloride ion into one compound, which is not accurate.

Question 15

Choose the polydentate ligand from the substances below.
A)thiocyanate ion
B)EDTA
C)nitrite ion
D)hydroxide ion
E)chloride ion

Accepted Answer

EDTA is a polydentate ligand as it has multiple donor atoms (four carboxylic groups and two amine groups) that can form multiple coordination bonds with a single metal ion. The other substances listed are monodentate ligands as they have only one donor atom that can form one coordination bond with a metal ion.

Question 16

Name the following: [Ni(NH₃)₃(H₂O)₃]Cl₂ A)nickel(II)trihydrotriamminechloride B)nickel(I)triamminetrihydrochloride C)dichloronickel(II)triamminetrihydride D)nickel(III)chloride E)triamminetriaquanickel(II)chloride

Accepted Answer

The complex contains nickel with a coordination number of 6. The ligands are triammine and two aqua ligands, along with two thiolates and one oxo ligand. The oxidation state of nickel is +2, as indicated by the Roman numeral in parentheses. The counterion is chloride. Therefore, the correct name for the complex is triamminetriaquanickel(II)chloride.

Question 17

Choose the bidentate ligand from the substances below.
A)ethylenediamine
B)EDTA
C)cyanide ion
D)ammonia
E)carbon monoxide

Accepted Answer

Ethylenediamine is a bidentate ligand because it has two nitrogen atoms that can donate lone pairs of electrons to a metal ion to form two covalent bonds. EDTA is a hexadentate ligand because it has six binding sites, cyanide ion is a monodentate ligand, ammonia is a monodentate ligand, and carbon monoxide is a strong sigma donor but a weak pi acceptor and can act as a monodentate or a bridging ligand.

Question 18

Determine the chemical formula for the compound hexaammineiron(III)hexacyanoferrate(III). A)[Fe₂(NH₃)₆(CN)₆]³⁺ B)[Fe(NH₃)₆][Fe(CN)₆]₂ C)[Fe(NH₃)₆]₃[Fe(CN)₆]₂ D)[Fe(NH₃)₆][Fe(CN)₆] E)[Fe₂(NH₃)₃(CN)₃]⁶⁺

Question 19

Identify the ion that is responsible for the green colour in emeralds. A)Cr⁺³ B)Cr⁺⁴ C)Cr⁺⁵ D)Cr⁺⁶ E)Cr⁺⁷

Accepted Answer

The ion responsible for the green colour in emeralds is Cr3+ (chromium ion with a charge of +3). In option A, the chromium ion is in its +3 oxidation state, which matches with the description. The other options have chromium ions with higher oxidation states, which would not produce a green colour.
