Overview of Bangla Chemistry Notes for Class 12

Below we have provided an overview of Bangla Chemistry class 12 notes -

1. THE SOLID STATE

This topic covers the structure and properties of solids, including crystalline and amorphous forms, types of unit cells, and packing in solids. It discusses defects in solids and their impact on material properties. The classification of solids based on binding forces is also introduced.

2. States of Matter

Students learn about the three main states—solid, liquid, and gas—and the intermolecular forces governing them. The gas laws, such as Boyle’s, Charles’s, and Avogadro’s laws, are explained. The kinetic molecular theory and deviations from ideal gas behavior are also discussed.

3. Solutions

This chapter introduces types of solutions, methods of expressing concentration (molarity, molality), and factors affecting solubility. It covers colligative properties like boiling point elevation and freezing point depression, along with their calculations.

4. s-Block Elements

Focuses on alkali and alkaline earth metals, their properties, trends in the periodic table, and important compounds. The reactivity, occurrence, and uses of these elements are highlighted, along with their biological significance.

5. REDOX REACTIONS

Redox reactions involve oxidation and reduction processes, electron transfer, and changes in oxidation number. The chapter explains balancing redox equations and their applications in daily life and industry.

6. Radioactivity and Nuclear Chemistry

This topic introduces radioactivity, types of radioactive decay, and nuclear reactions. Students learn about the concept of half-life, nuclear fission, and fusion, though these are generally covered in more detail in higher classes.

7. Ionic Equilibrium

Ionic equilibrium deals with the dissociation of electrolytes, the concept of acids and bases, and pH calculations. It covers buffer solutions and solubility product, though this is more detailed in Class 12. 

8. HYDROGEN and Surface Chemistry

Hydrogen discusses its occurrence, properties, and compounds like water and hydrogen peroxide. Surface chemistry, generally a Class 12 topic, covers adsorption, catalysis, and colloids.

9. HALOALKANES AND HALOARENES

These are organic compounds containing halogens. The chapter covers their nomenclature, preparation, properties, and uses, but is mainly part of the Class 12 syllabus.

10. ELECTROCHEMISTRY

Electrochemistry deals with redox reactions in electrochemical cells, electrode potentials, and their applications. This topic is typically studied in Class 12.

11. d and f-Block Elements

These transition and inner transition elements are discussed in terms of properties, electronic configuration, and uses, but this is part of the Class 12 syllabus.

 12. Coordination Compounds

Focuses on complex compounds, their nomenclature, bonding, and applications, which are covered in detail in Class 12.

13. Chemical Thermodynamics

Introduces energy changes in chemical reactions, concepts of enthalpy, entropy, and Gibbs free energy. It explains the laws of thermodynamics and their application to chemical processes.

14. CHEMICAL KINETICS

Chemical kinetics studies the rate of chemical reactions, factors affecting them, and the concept of activation energy. This is a Class 12 topic. 

15. Chemical Equilibrium

Explains reversible reactions, the law of mass action, and the concept of equilibrium constant. It covers Le Chatelier’s principle and its applications in chemical systems.

16. Alcohols, Phenols & Ethers

These are classes of organic compounds. The chapter covers their structure, preparation, properties, and uses, but is mainly included in Class 12.

17. Polymers

Polymers are large molecules made from repeating units. The topic covers types of polymers, methods of polymerization, and their uses, generally in Class 12.

18. Chemistry in Everyday Life

This topic discusses the role of chemistry in daily life, including drugs, detergents, food additives, and more. It is typically a Class 12 chapter.

19. Biomolecules

Biomolecules include carbohydrates, proteins, lipids, and nucleic acids, focusing on their structure and biological functions. This is also part of the Class 12 syllabus.
