Class 11 Chemistry

14 Chapters

Class 11


Class 11 Chemistry covers some of the basic yet important concepts, which help students to understand chemistry more clearly. Moreover, the book has 14 chapters which help students in grasping chemistry easily. Chapter 1 teaches about some of the basic concepts of chemistry such as atomic and molecular masses, the importance of chemistry, and some others. Chapter 2 explains the structure of the atom and subatomic particles. Chapter 3 describes the classification of elements and periodicity in properties of elements, and s, p, d, f shells, and more. Chapter 4 teaches about molecular structure and chemical bonding. Chapter 5 teaches states of matter like partial pressure, Gas laws, etc. Chapter 6 defines thermodynamics and related concepts. Chapter 7 is about equilibrium such as ionic equilibrium, equilibrium constant, etc. Chapter 8 teaches the redox reaction that is oxidation and reduction reaction. Chapter 9 gives some information about hydrogen, its properties, uses, compounds, hydrides, and some more related topics. Chapter 10 depicts the s-blocks elements what are they and different things and properties relating to them. Chapter 11 is about p-block elements, characteristics, and classification. Chapter 12 relates to organic chemistry- some of its basic principles and techniques. Chapter 13 explains hydrocarbons, its classification, alkynes, alkanes, etc. Lastly, chapter 14 teaches about environmental chemistry, which means the entire chemical compounds that we can find in nature.

Chapter 2 : Structure of Atom

Everything we see around us is made up of something. For instance, table is made from wood, wood in-turn comes from trees and, trees come from seed. Now, these seeds are made up of tiny matter called 'Atom'. But what is an atom made of? Let us find out.

Chapter 3 : Classification of Elements and Periodicity in Properties

Have you ever seen the chemistry periodic table? It looks daunting, right? There are so many elements that we can't even remember. But it becomes easier to remember them when we break the table into groups and study the properties and classification of elements. Want to learn about these properties and the

Chapter 4 : Chemical Bonding and Molecular Structure

Do you ever wonder how elements actually bond to form a compound? Is it like humans wherein they just get attracted? Or is it like planets wherein there is a force that just holds them together? If you do, you have come to the right place. Let's learn about Chemical Bonding and Molecular Structure in detail.

Chapter 5 : States of Matter

Matter is all around us. You are reading this on a matter and you yourself are a matter. But do you know whether a matter can change its stage? What are the characteristics of particles of matter? What is evaporation? How many states of matter exist? Let's find out more about the matter in our surroundings.

Chapter 7 : Equilibrium

Equilibrium, as the name suggests, refers to as balance. In chemistry, chemical equilibrium refers to the state in which the concentration of the reactants and products won't change. In this chapter, we will learn everything about Equilibrium and lot more.

Chapter 8 : Redox Reactions

Do you realize that a redox reaction might be happening around you right now? Yes! The rusting of iron, burning, the decay of a substance are all nothing but redox reactions. But what actually happens in a redox reaction? What does the term 'redox' even mean? Do you want to know? Then hop on this train

Chapter 9 : Hydrogen

Did you know that Hydrogen does not belong to any group or family in the Periodic Table? It has such unique properties that are not similar to any other element on our planet. Almost two-thirds of our Universe's mass is composed of this unique element!  Let us learn about hydrogen and some of its important compounds.

Chapter 10 : The s-Block Elements

Out of all the elements in the periodic table, the s block elements are the most known and used elements. Elements like calcium, sodium and potassium are all members of the s block. I'm sure you have heard these names in your house. They are very useful elements.All the other elements of the s block

Chapter 11 : Some p-Block Elements

Which is your favourite element? Oxygen or Nitrogen? Oxygen of course. Isn't it? How would you live without it? But did you know that 78% of air consists of nitrogen? They both are p block elements and are equally important. Wonder what other elements are present in the p block of the periodic table?

Chapter 12 : Organic Chemistry - Some Basic Principles and Techniques

Do you know that Chemistry has two branches? Yes. They are- Inorganic and Organic Chemistry. While inorganic chemistry includes all elements, organic chemistry studies compounds of Carbon. Why is carbon so important that it is studied under a different branch? What are its unique properties?

Chapter 13 : Hydrocarbons

When it comes to flavors, the most basic flavor anyone might remember is 'Vanilla'. Isn't it? Even though it's so basic, one has still not been able to crack its exact composition. But we'll let you on in a secret! The secret ingredient vanilla is the addition of a 'Hydrocarbon'. So what is it? Let us know more!

Chapter 14 : Environmental Chemistry

You must be thinking what does chemistry have to do with the environment? Environmental Chemistry is the study of chemicals as they pass through our environment and the effects they cause on the air, water, soil etc. It is an important field of study as it helps us trace and control contaminants. Let us take a look.
