There are 14 chapters in the NCERT 11 Chemistry book. It covers topics such as Atoms, redox reactions, thermodynamics, states of matter, hydrocarbons, environmental chemistry, and others. Furthermore, if you are studying for any competitive examinations such as NEET, JEE, or other similar exams, NCERT Books for Class 11 Chemistry will surely come in handy.
Chapter 1- Some Basic Concepts of Chemistry
This chapter will cover the fundamentals of chemistry. Essentially, this is the first chapter in the class 11 curriculum. This chapter starts with an introduction and then moves on to a discussion of the subject’s history.
Following that, it carries on to a discussion of the relevance of chemistry and the nature of many topics. State and categorization are two subsections of the type of things section. This chapter also covers chemical combination laws, atomic and molecular masses, properties of matter, atomic theory, measurement uncertainty, Dalton’s atomic theory, and more.
There are various pictures in this chapter of Class 11 Chemistry NCERT and an exercise part at the conclusion. It will assist you with a better comprehension of the material.
Chapter 2 – Structure of Atom
Atoms are the building blocks of all elements. They are the tiniest bits of any element that may react chemically. Since 400 B.C., Indian and Greek philosophers have suggested the existence of atoms. Nonetheless, in 1808, British physicist John Dalton presented the first atomic hypothesis. Atoms, according to his conception, were indivisible matter particles.
However, by the end of the nineteenth century, his idea had been disproved. During this period, experiments revealed that atoms are made up of three basic parts: electron, proton, and neutron. The discovery of subatomic particles resulted in the development of many atomic models that described atomic structures.
Furthermore, you will study about these atomic structures in detail in the chapter of NCERT for Class 11 Chemistry, and the exercise part will help you review your knowledge.
Chapter 3 – Classification of Elements and Periodicity in Properties
The periodic table is, without a doubt, a vital concept in chemistry. You will learn about it in this chapter of the NCERT books for class 11 chemistry. This section also covers the history of the periodic law and the periodic table.
Mendeleev had previously suggested a table based on atomic mass. On the other hand, the new one organizes atoms by atomic number in seven horizontal rows (periods) and eighteen vertical columns (groups or families). In addition to this table, you’ll also learn about periodic classifications, which are a logical result of an atom’s electrical configuration.
Following that, you’ll look at numerous periodic patterns in the chemical and physical characteristics of several elements.
Chapter 4 – Chemical Bonding and Molecular Structure
Every substance is made up of numerous elements, and under normal conditions, no element can exist as an isolated atom. In contrast, noble gases are an exception.
On the other hand, Molecules are a collection of atoms that exist together and have distinct features. Chemical bonds are the attractive forces that keep these atoms together.
The bonds and structures of different atoms are explored in this chapter of NCERT class 11 chemistry book. It includes a detailed examination of each topic in this chapter and pertinent examples and pictures. As a consequence, you will have a lot easier time understanding this somewhat challenging chapter.
Chapter 5 – States of Matter
You’ve previously learned about the characteristics of a single particle. Atomic size, electronic charge density, ionization enthalpy, polarity, and molecular structure are only a few examples. The visible qualities of diverse components always reflect bulk attributes. This indicates that these characteristics are linked to a massive number of atoms, molecules, or ions. In a nutshell, you may see the properties of a material in a particular condition.
However, you should be aware that the chemical characteristics of substances do not change as a result of their present condition. Their reactivity, on the other hand, may differ.
You will learn about the different physical matter of substances and their features in this fifth chapter of class 11 NCERT Chemistry Textbook.
Chapter 6 – Thermodynamics
Molecules collect chemical energy, which they emit during a chemical reaction. This energy serves a variety of functions. It can do mechanical tasks, as well as assist other reactions. As a result, these many sources of energy are interconnected, but only under certain situations. They may also be transferred from one form to another.
Thermodynamics is the study of this energy transformation. The rules of thermodynamics look at energy changes in macroscopic systems with a large number of molecules rather than microscopic systems with a smaller number of molecules.
This chapter of thermodynamics will cover terminology, heat measurement, spontaneity, and other topics. Additionally, to go through this chapter, use the exercise portion at the end of this chapter of your class 11 chemistry NCERT textbook.
Chapter 7 – Equilibrium
Chemical equilibrium refers to a situation in which both reactants and products are present in equations that do not vary over time. As a result, no changes in their attributes are seen. When a forward reaction and a backward reaction both continue at the same pace, equilibrium is reached.
However, this reaction of backward and forward responses is not zero; instead, it is equal. As a consequence, neither the reactants nor the products’ concentrations change. It’s referred to as dynamic equilibrium.
You will study everything about it in this chapter of Class 11 Chemistry NCERT books. The law of equilibrium and its constants are discussed in this chapter, as well as equilibrium in physical and chemical processes. There are also illustrations and equations to help you grasp this chapter in a better manner.
Chapter 8 – Redox Reactions
The goal of chemistry is to study and portray the transformation of matter from one kind to another. This transition takes place via a series of responses. Redox reactions are one of the most common types of such reactions. In redox processes, oxidation and reduction occur simultaneously.
In addition, there are four types of redox reactions: combination, decomposition, displacement, and disproportionation. This chapter also covers redox couple and electrode processes, in addition to their varieties. Redox reactions are used in a variety of fields, including pharmaceuticals, agriculture, and metallurgy.
Further, the equations and questions included in this chapter of NCERT chemistry class 11 book will enable you to understand the concepts of this chapter in a more effective way.
Chapter 9 – Hydrogen
Hydrogen has the simplest atomic structure of all the elements in the periodic table, as well as in nature. It has one proton and one electron in its atomic form. It is, on the other hand, a diatomic molecule known as hydrogen in its basic form.
In nature, hydrogen generates more compounds than any other element. On the periodic table, it is also the first element. Hydrogen is also very relevant in the industrial aspects.
You will learn about hydrogen, dihydrogen, their properties, preparations, and hydrides in this chapter of the NCERT 11 chemistry book. To learn more about these concepts, complete the exercise part.
Chapter 10 – The s-Block Elements
The final electron in an s-block element enters the most distant s-orbital. Groups one and two of the periodic table belong to this division because the outermost s-orbital can only hold two electrons.
Lithium, sodium, rubidium, potassium, cesium, and francium belong to the first category. These are commonly used alkali metals. On the other hand, the second category includes elements like beryllium, calcium, magnesium, strontium, radium, and barium. Except for beryllium, these elements are classified as alkaline earth metals.
Besides, you will study these elements in depth in this chapter of the NCERT Class 11 chemistry textbook. You’ll also look at their qualities and how they’re used. Additionally, completing the exercise section will aid you in perceiving these s-Block features much more efficiently.
Chapter 11 – The p-Block Elements
The final electron in a p-Block element reaches the furthest p-orbital. A set of six electrons may fit into one p-orbital since there are three of them. As a result, the periodic table has a total of six such groupings of elements. It has a numeric range of 13 to 18.
Chapter 11 of the NCERT textbook for Class 11 Chemistry describes this set of elements in more depth. Learn their attributes and their uses also from this chapter.
