Chapter 1 THE SOLID STATE

This chapter deals with the solid state. It is comprised of 11 subtopics. This chapter deals with crystalline and amorphous solids, as well as imperfections in solids. It explains the unit cell in detail, and then builds up to explain the solid state. The solutions are made in accordance with the NCERT text. It justifies the concepts explained in the textbook, and helps the students reinforce the fundamentals.

CHAPTER 2 SOLUTIONS

The second chapter deals with types of solutions, and their properties. The concepts dealt with are Raoult’s law, concentration of solutions, vapor pressure of liquid solutions, abnormal molar masses, and colligative properties. The back and in-chapter exercises are made to reinforce the concepts, and the solutions aid the students in the same. This chapter promises a chunk of 5 marks in the Board exam.

CHAPTER 3 ELECTROCHEMISTRY

This chapter deals with the electrochemical cell. Students also learn about the galvanic cell and the electrolytic cell. The chapter explains the standard potential of the cell, Gibbs energy of cell reaction, and the relation with the equilibrium constant. The students will learn the Kohlrausch Law and its applications.

CHAPTER 4 Chemical Kinetics

This chapter tells about the kinetics, or the rate of a reaction. The topics covered include the factors affecting the rate of a reaction, the integrated rate equation, Pseudo First Order reactions, and the collision theory of chemical reactions. This chapter is permissible for engineering and medical sciences point of view too.

CHAPTER 5 SURFACE CHEMISTRY

The fifth chapter explains you about  emulsions, adsorption, adsorption isotherms, factors controlling adsorption of gases and liquids, and catalysts and their role in industry and our day to day life. The chapter further explores colloids and their applications.

CHAPTER 6 General Principles and Processes of Isolation of Elements

This chapter deals with the inorganic chemistry portion of the syllabus. The chapter explores the occurence of metals, the process of concentration of different types of ores, cleaning and extraction of crude metal from ores, thermodynamic and electrochemical principles of metallurgy, and the refining process used in the industry.

CHAPTER 7 THE P-BLOCK ELEMENTS

The chapter explains the Group 15 elements, Oxides of Nitrogen, Allotropes of Phosphorus, Group 16 elements, simple oxides, allotropes of sulfur, chlorine, and other elements. The questions generally are 1 marker and based on chemical equations.

CHAPTER 8 THE D AND F BLOCK ELEMENTS

The chapter explains you the properties of transition elements, colored ions and complex compounds, variation in sizes of elements, ionization enthalpies, magnetic properties, and oxidation states. The chapter deals with d block elements and their properties and variations.

CHAPTER 9 COORDINATION COMPOUNDS

The students are required to pay special attention to the chapter. The chapter explains Werner’s theory of Coordination compounds, Bonding in Coordination compounds, Nomenclature, Isomerism and others. The chapter can be well understood through the exercises and solutions, that help to reinforce the fundamentals. Students must focus on the nomenclature of the compounds.

CHAPTER 10 HALOALKANES AND HALOARENES

This is the official start of the organic chemistry. Students learn the concepts of IUPAC nomenclature of Haloalkanes and Haloarenes. They will also learn the applications of organometallic reactions, preparation of haloalkanes and haloarenes, and stereochemistry. The students also learn to design the reaction mechanism.

CHAPTER 11 Alcohol, Phenol and Ethers

This chapter also begins with the IUPAC nomenclature of alcohols, phenols and ethers. They also deal with the preparation of alcohols, phenols, and ethers. They further explore the properties of the same.

CHAPTER 12 Aldehydes, Ketones and Carboxylic Acids

The next chapter is the aldehydes, ketones and carboxylic acids. The IUPAC names, to start with, the chapter explores their preparation methods, the key reactions, characteristic tests, and other properties.

CHAPTER 13 AMINES 

The ten subtopics include the preparation methods, the physical properties, the chemical reactions, the methods to prepare diazonium salts, the importance of diazonium salts in synthesis of Aromatic Compounds. It is one of the easiest chapter to score if ample amount of time is given to this chapter.

CHAPTER 14 BIOMOLECULES

In this chapter, students learn about biomolecules like glucose, fructose, starch, glycogen, etc. They get to learn about the structure, the classes, and the properties of carbohydrates and proteins. They also learn about the reactions of some biomolecules.

CHAPTER 15 POLYMERS

This chapter deals with the science of polymers, the various types of polymers, whether addition or condensation, linear or cross linked, their reactions, and their properties. This chapter also deals with some well known polymers and their applications. Again one of the easiest chapter, questions generally comes about the structure and components of the polymers.

CHAPTER 16 CHEMISTRY IN EVERYDAY LIFE

This chapter deals with the importance of chemistry in everyday life, mainly drug action, drug classification and uses, and the target interaction, along with chemicals in food and cleansing agents.
