What is Chemistry?

Chemistry is the branch of science that studies matter. A matter is anything and everything that you can see, feel, touch or experience for example a book, table, air, rock, tree etc. Chemistry studies the composition of these matters, what are they made up of, the change that happen when they are heated up or cooled.

Chemistry is subdivided into three main parts

• Physical Chemistry
• Inorganic Chemistry
• Organic Chemistry

Physical chemistry is the study of macroscopic properties, atomic properties, and phenomena in chemical systems. In physical chemistry, we study rates of chemical reactions, the energy transfers that occur in reactions, or the physical structure of materials at the molecular level.

Inorganic chemistry is the study of chemicals that do not, in general, contain carbon. Inorganic chemicals are commonly found in rocks and minerals. One current important area of inorganic chemistry deals with the design and properties of materials involved in energy and information technology.

Organic chemistry is the study of chemicals containing carbon with hydrogen. Carbon is one of the most abundant elements on Earth and is capable of forming a tremendously vast number of chemicals. Most of the chemicals found in all living organisms are based on carbon.

Class 11 Chemistry NCERT Chapter 5 Thermodynamics

Chapter 5 is mainly related to the physical changes of the surrounding system and produces, which are used in the chemical reaction. Thermodynamics mostly deals with the energy exchange during the chemical process: isothermal, endothermic, and exothermic. Students will get to learn about various topics related to thermodynamic terminology, such as enthalpy, entropy, latent heat, specific heat, and more. Students can check the information about the topics discussed in the chapter below.

Thermodynamics: Topics Covered

Class 11 Chemistry NCERT Chapter 6 Equilibrium

Chapter 6 Chemical Equilibrium is an important chapter to learn more about the reaction mechanism of the Chemical reactions. Students will also learn the concepts related to the equilibrium state of a chemical reaction. Equilibrium is a state where the rate of forward and backward reactions become equal. Students can check the important topic of discussion in this chapter.

Equilibrium: Topics Covered

Class 11 Chemistry NCERT Chapter 7 Redox Reaction

Chapter 7 Redox reactions deal with types of chemical reactions that are abundant and easy to observe, chemical reactions where oxidation (loss of electrons) and reduction (gain of electrons) happen together.  Students can observe redox reactions on many occasions in everyday life, such as rusting, combustion, and metabolism. Students can check the important topics of discussion for Redox Reactions below:

Redox Reaction: Topics Covered

Class 11 Chemistry NCERT Chapter 8 Organic Chemistry- Some Basic Principles & Techniques

Chapter 8 Organic Chemistry deals with carbon, its chemical properties, and carbon compounds. Carbon has a unique property called catenation, which allows carbon to form chains with other carbon atoms and form covalent bonds with atoms of other elements like hydrogen, oxygen, nitrogen, and halogens. All Carbon compounds are studied under a separate branch of chemistry called organic chemistry. Students can check the important topics of the chapter below:

Organic Chemistry- Some Basic Principles & Techniques: Topics Covered
