The Chemistry of d- and f- Block: The Chelate Effect

In this section, we will build up one of the concept of the trend in stability constant where changing the ligands into chelating agent has effect on the stability constant. A chelating agent or a chelate can be defined as polydentate ligand where it has more than 1 attachment point of ligand-metal ion. In this section, we will also see the origin and the physical interpretation of the chelate effect.

The Chemistry of d- and f- Block: Complex Synthesis and Stability Constant

In this section, we will have a discussion how to make a complex compound through some common methods or reactions such as substitution or redox reaction. Besides that, we will also see some thermodynamics and kinetics aspect in complexation reaction, one of the thermodynamics parameter which will be discussed is the stability constant, K. Lastly, we will also see the pattern of K in complexation reaction with some abnormal cases.

The Chemistry of d- and f- Block: Thermodynamics Consequences of CFSE

In this section, we will build up again the concept of CFSE as we will look the consequences over CFSE into some observable values, such as hydration enthalpy of M²⁺ and ionic radius of M²⁺ ions. Besides that, we can also determine from the value of Δ_o from hydration enthalpy. In this section also, we will look how CFSE could be used to predict the geometry of coordinated complex to be a tetrahedral or a octahedral complex.

The Chemistry of d- and f- Block: Th Absorption Spectrum of Complex Compounds

In this section, we will have a discussion for one of the consequences of crystal splitting (CFSE) stabilisation energy which is observed in a spectrum. In this section, we will explain some unique characteristics of complex compound's absorption spectrum. Furthermore, we will also see Jahn-Teller distortion which gives the unique pattern of absorption spectrum of a complex compound.

Radicals and Us II: Radicals in Life

In this section, we will continue our discussion in radicals and we will discuss about the radicals in our life. In this case, we will see how radicals play prominent roles in antioxidant and immune system of body, and also in the atmosphere as it affects the climate of the Earth.

The Chemistry of d- and f- Block: The Origin of Colour in Complexes, Magnetism, and Isomerism

In this section, we will have a discussion about the consequences of crystal field theory which is the colour in complexes and magnetism. In this discussion, the crystal field theory will rationalise the origin of both properties. Furthermore, the geometry of complexes could also form the isomerism which can give different characters of complexes.

The Chemistry of d- and f- Block: Crystal Field Theory

In this section we will build up our understanding in d-block complex compounds by looking the bonding in complex compounds. One of the approach is by using the crystal field theory which can derive some important properties of complexes. Then, we will see some factors that affect the crystal field splitting such as the ligands and the metal centre ion.

Radicals and Us I: the Fundamentals and Polymer Manufacture

In this section we will explore the chemistry behind the radicals and how radicals relate closely in our world. This part we will explore the fundamentals of radical which include how to generate radical and their stability. After that, we will see how radicals can be used in daily life, mainly in polymer synthesis.
