Interpretation Introduction

Interpretation:

The crystal field splitting of the given structures to be interpreted.

Concept Introduction:

Spectrochemical series: The list of ligands arranged in an ascending order of (Δ)(the splitting of d-orbitals in presence of various ligands).

I-<Br-<SCN-<Cl-<S2-<F-<OH-<O2-<H2O<NCS-<edta4-<NH3<  en<NO2-<CN-<COweak-fieldincreasing(Δ)strong-fieldligandsligands

Crystal field splitting: The energy gap between the splitting of d-orbitals of the metal ion in presence of ligands is known as the crystal field splitting (Δ). The magnitude of (Δ) is depends on the nature of metal ions and the ligands.

To Identify: The crystal field splitting of the given structures to be interpreted.

Orbital Splitting diagram of linear complex:

In the linear structure, the ligands which are pointing directly towards the z-axis, the dz2 orbital of the metal ion gains highest energy. The dxz,dyz orbitals are equivalent in energy which lies below, and dx2-y2,dxy both exhibits similar energy gains the least energy in the splitting.

Orbital Splitting diagram of trigonal complex:

In the trigonal structure, the ligands which are pointing directly towards the x-axis and y-axis, the dx2-y2,dxy orbitals of the metal ion gains highest energy (because the ligands are present in the xy –plane). The dxz,dyz orbitals are equivalent in energy which lies below, and dz2 orbitals exhibits least energy (because along the z-axis no ligands are present) in the splitting.

Orbital Splitting diagram of trigonal bipyramidal complex:

In the trigonal bipyramidal structure, the ligands which are pointing directly towards the z-axis, the dz2 orbital of the metal ion gains highest energy. The dx2-y2 ,dxy orbitals are equivalent in energy which lies below (because the ligands are present in the xy –plane), and dxz,dyz orbitals exhibits least energy (because along the z-axis two ligands are present but on the xy-plane three ligands are present) in the splitting.

30. We will derive the forms of the molecular partition functions for atoms and molecules shortly in class, but the partition function that describes the translational and rotational motion of a homonuclear diatomic molecule is given by Itrans (V,T) = = 2πmkBT h² V grot (T) 4π²IKBT h² Where h is Planck's constant and I is molecular moment of inertia. The overall partition function is qmolec Qtrans qrot. Find the energy, enthalpy, entropy, and Helmholtz free energy for the translational and rotational modes of 1 mole of oxygen molecules and 1 mole of iodine molecules at 50 K and at 300 K and with a volume of 1 m³. Here is some useful data: Moment of inertia: I2 I 7.46 x 10- 45 kg m² 2 O2 I 1.91 x 101 -46 kg m²
