(a)

Interpretation Introduction

Interpretation:

The complex that have greater crystal field splitting has to be given from give set of complexes, [Rh(NH3)6]3+ or [Rh(CN)6]3-.

(a)

Expert Solution
Check Mark

Explanation of Solution

Crystal field splitting energy is a requited energy to split the d orbitals in to t2gorT2andegorE levels.

The strong ligands are split d orbitals in to t2gorT2andegorE levels for greater extent so the complexes having greater crystal field splitting.

If two complexes containing same metal means, the higher positive charged metal has a greater crystal field splitting and other than 4th period transition elements having greater crystal field splitting in the order or up to down in the periodic table.

Reason for the correct option:

[Rh(CN)6]3- complex has stronger ligand so it has greater crystal field splitting from given set of complexes.

Reason for the incorrect option:

In [Rh(NH3)6]3+ complex, NH3 is weaker ligand than CN so it has lesser crystal field splitting.

(b)

Interpretation Introduction

Interpretation:

The complex that have greater crystal field splitting has to be given from give set of complexes, t2gorT2andegorE.

The strong ligands are split d orbitals in to t2gorT2andegorE levels for greater extent so the complexes having greater crystal field splitting.

If two complexes containing same metal means, the higher positive charged metal has a greater crystal field splitting and other than 4th period transition elements having greater crystal field splitting in the order or up to down in the periodic table.

Reason for the correct option:

[Fe(H2O)6]3+ complex has higher charge so it has greater crystal field splitting from given set of complexes.

Reason for the incorrect option:

In [Fe(H2O)6]2+ complex, lesser charge so it has lesser crystal field splitting.

(c)

Interpretation Introduction

Interpretation:

The complex that have greater crystal field splitting has to be given from give set of complexes, [Co(H2O)6]3+ or [Rh(H2O)6]3+ .

Reason for the correct option:

[Rh(H2O)6]3+ complex has 5th period metal so it has greater crystal field splitting from given set of complexes than [Co(H2O)6]3+.

Reason for the incorrect option:

In [Co(H2O)6]3+ complex, has 4th period transition metal so it has lesser crystal field splitting than [Rh(H2O)6]3+.

(d)

Interpretation Introduction

Interpretation:

The complex that have greater crystal field splitting has to be given from give set of complexes, [TiF6]3- or [Ti(H2O)6]3+ .
