Classification of Elements and Periodicity in Properties:
This section covers the modern periodic table and the periodic trends of elements. Topics include atomic and ionic radii, ionization enthalpy, electron gain enthalpy, electronegativity, valence, and oxidation states.
4
Chemical Bonding and Molecular Structure:
This is a crucial topic that extends beyond just inorganic chemistry, but a deep understanding of bonding is essential. It includes theories like VSEPR, valence bond theory, and molecular orbital theory, as well as concepts like hybridization, resonance, and dipole moment.
5
Coordination Compounds:
This sub-part focuses on complex compounds. Key topics include Werner's theory, IUPAC nomenclature, isomerism (cis-trans, ionization), bonding theories (Valence Bond Theory and Crystal Field Theory), magnetic properties, and the color of coordination compounds.
5
s-Block Elements:
This section deals with the alkali and alkaline earth metals (Groups 1 and 2). It covers their general characteristics, reactivity towards various substances, and the properties of their compounds
5
p-Block Elements:
This is a large and important section covering groups 13 to 18. It details the electronic configuration, general trends in physical and chemical properties, anomalous behavior of the first element in each group, and the preparation, properties, and uses of important compounds of these elements.
7
d- and f-Block Elements:
This section focuses on transition elements (d-block) and inner transition elements (f-block). It includes general characteristics, electronic configuration, and trends in properties like ionization enthalpy, oxidation states, and magnetic properties.
5
Principles of Qualitative Analysis:
This topic, also known as salt analysis, involves the identification of cations and anions. It's an experimental chemistry topic that requires an understanding of the reactions and principles involved in separating and confirming the presence of different ions.
6
Metallurgy (General Principles and Processes of Isolation of Elements):
This part covers the general methods of extracting metals from their ores, including topics like concentration, reduction, refining, and the principles behind these processes

Lesson 3: Isomerism in Coordination Compounds

This lesson explores the different ways in which coordination compounds can have the same molecular formula but different arrangements of atoms.

- Structural Isomerism: This type of isomerism arises from differences in the bonds within the coordination entity.
  - Ionization Isomerism: Isomers that produce different ions in solution. For example, $[C o (N H_3)_5 B r] SO_4$ and $[C o (N H_3)_5 SO_4] B r$ .
  - Hydrate Isomerism: Isomers that differ in the number of water molecules inside and outside the coordination sphere.
  - Linkage Isomerism: Occurs with ambidentate ligands (ligands that can bond through different donor atoms), such as $NO_2^{-}$ (nitro) and $ON O^{-}$ (nitrito).
- Stereoisomerism: This type of isomerism involves the same bonds but different spatial arrangements.
  - Geometrical Isomerism (cis-trans): This is common in complexes with coordination numbers 4 and 6. For example, in a square planar complex like $[Pt (N H_3)_2 Cl_2]$ , the ligands can be adjacent (cis) or opposite (trans).

* **Optical Isomerism**: Occurs when a coordination compound is non-superimposable
