Class XI

This chapter gives a general introduction to hydrogen. Properties of hydrogen, preparation of dihydrogen, hydrides, and water- structure and properties are discussed. It also talks about Hard, Soft, and Heavy Water, and the Uses of Dihydrogen.

This chapter provides an overview of organic chemistry. We learn about the fundamental concepts and types of organic reactions. It also discusses the classification, IUPAC nomenclature, and qualitative and quantitative analysis of organic compounds.

This chapter provides an overview of Hydrocarbons and their classifications. We will learn about the preparation method, physical and chemical properties of Alkanes, Alkenes, and Alkynes. It also discusses isomerism in Alkanes, Alkenes, and Alkynes.

This chapter talks about the matter and its nature, the laws of chemical combination, and Dalton’s atomic theory. We also learn about atomic and molecular mass, empirical and molecular formulae, properties of matter, and stoichiometry.

This chapter talks about the fundamentals and terminologies in thermodynamics. The first, second, and third laws of thermodynamics and their applications are described. We also learn about the enthalpy change of a reaction and Gibbs energy change.

This chapter explains atomic models, the discovery of subatomic particles, the particle nature of electromagnetic radiation, and the photoelectric effect. It also discusses Bohr's Model for the Hydrogen Atom, Quantum Mechanical Model of the Atom.

This chapter discusses the Kossel-Lewis approach to chemical bonding. We learn about ionic or electrovalent bond and bond parameters and the concept of hybridisation. It also explains the concept of resonance, polarisation and dipole Moment.

This chapter discusses the classification of states of matter. We study the measurable properties of gases, intermolecular forces, gaseous laws, and ideal gas equation. It also explains the Van der Waals Equation and Dalton's law of partial pressure.

This chapter gives a brief history of the development of the periodic table. Modern periodic law, classification of the period table, and valency and oxidation states are discussed. It also talks about atomic, ionic, and Van der Waals radii.

The chapter discusses ionic equilibrium in solution, ionization of acids and bases, and solubility equilibria of sparingly soluble salts. We study the concepts of acids, bases and salts, the ionic product of water, pH scale, and equilibrium constant.

In this chapter, we learn about redox reactions. Redox reactions and titration and redox reactions and electrode processes are discussed. It explains the concepts of oxidation and reduction, oxidation number, and types of redox reactions.

This chapter provides us with the general introduction of group 1 and 2 elements. We explore the physical and chemical properties, uses, and important compounds of group 1 and 2 elements. It also comprises examples of elements of these groups.

In this chapter, we will learn about p-block elements. It gives an overview of group 13-18 elements, their important compounds, and their chemical and physical properties. It also briefs us on the atomic properties and uses of group 15-17 elements.

This chapter talks about environmental chemistry. Different pollutions such as environmental, atmospheric, water pollution, and soil pollution are discussed. It also explains strategies to control environmental pollution and industrial waste.
