Chapter 23, Problem 23.86P

(a)

Interpretation Introduction

Interpretation:

The $T{i}^{3+}$ ions cannot form both high and low-spin octahedral complex has to be determined.

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

  $\left[noblegas\right]n{s}^2\left(n-1\right)d^x.$

(b)

Interpretation Introduction

Interpretation:

The $C{o}^{2+}$ ions cannot form both high and low-spin octahedral complex has to be determined.

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

  $\left[noblegas\right]n{s}^2\left(n-1\right)d^x.$

(c)

Interpretation Introduction

Interpretation:

The $F{e}^{2+}$ ions cannot form both high and low-spin octahedral complex has to be determined.

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

  $\left[noblegas\right]n{s}^2\left(n-1\right)d^x.$

(d)

Interpretation Introduction

Interpretation:

The $C{u}^{2+}$ ions cannot form both high and low-spin octahedral complex has to be determined.

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

  $\left[noblegas\right]n{s}^2\left(n-1\right)d^x.$
