Chapter 23, Problem 23.88P

(a)

Interpretation Introduction

Interpretation:

For the given complex the orbital splitting diagram has to be drawn using spectrochemial series.

  [Cr(H2O)6]3+

Concept introduction:

The element in the periodic table and count its position in the respective transition series. These elements are in Periods 5 and 6, so the general configuration is

  [noble gas]ns2(n 1)dx.

The spectrochemical series is

  I<Cl<F<OH<H2O<SCN<en<NO2<CN<CO

(a)

Expert Solution
Check Mark

Explanation of Solution

Electron configuration of Cr: [Ar]4s13d5

Charge on Cr: The aqua ligands are neutral, so the charge on Cris+3.

Electron configuration of Cr3+: [Ar]3d3

Six ligands indicate an octahedral arrangement.  Using Hund’s rule, fill the lower energy

t2g orbitals first, filling empty orbitals before pairing electrons within an orbital.

(b)

Interpretation Introduction

Interpretation:

For the given complex the orbital splitting diagram has to be drawn using spectrochemial series.

  [Cu(H2O)4]2+

Concept introduction:

The element in the periodic table and count its position in the respective transition series. These elements are in Periods 5 and 6, so the general configuration is

  [noble gas]ns2(n 1)dx.

The spectrochemical series is

  I<Cl<F<OH<H2O<SCN<en<NO2<CN<CO

(b)

Expert Solution

Explanation of Solution

Electron configuration of Cu: [Ar]4s13d10

Charge on Cu: The aqua ligands are neutral, so Cu has a +2 charge.

Electron configuration of Cu2+: [Ar]3d9

Four ligands and a d9 configuration indicate a square planar geometry (only filled d sublevel ions exhibit tetrahedral geometry).  Use Hund’s rule to fill in the nine d electrons.  Thus, the correct orbital-energy splitting diagram shows one unpaired electron.

(c)

Interpretation Introduction

Interpretation:

For the given complex the orbital splitting diagram has to be drawn using spectrochemial series.

  [FeF6]3

Concept introduction:

The element in the periodic table and count its position in the respective transition series. These elements are in Periods 5 and 6, so the general configuration is

  [noble gas]ns2(n 1)dx.

The spectrochemical series is

  I<Cl<F<OH<H2O<SCN<en<NO2<CN<CO

(c)

Expert Solution

Explanation of Solution

Electron configuration of Fe: [Ar]4s23d6

Charge on Fe: Each fluoride ligand has a –1 charge for a total charge of –6, so Fe has a +3 charge to make the overall complex charge equal to –3.

Electron configuration of Fe3+: [Ar]3d5

Six ligands indicate an octahedral arrangement.  Use Hund’s rule to fill the orbitals.

F– is a weak-field ligand, so the splitting energy, Δ, is not large enough to overcome the resistance to electron pairing.  The electrons remain unpaired, and the complex is called high-spin.
