Now we are going to analyze every single Unit:-

Unit-1 Some Basic Concepts of Chemistry- This unit explains the importance of chemistry in our daily life. This unit briefs the students about fundamental concepts of the subject like – states of matter, Classification of matter, properties of matter and their measurement like mass and weight, volume, density, temperature. This chapter further explains an atomic theory, the law of chemical combinations, chemical reactions, the law of dilution, Stoichiometry, the mixture of acids and bases, normality, the law of chemical equivalence, etc.

Unit-2 Structure of Atom-  This unit deals with the various advancements being made to explain different atomic models which gave a modern structure of atoms. In this unit, students will get to know about the discovery of fundamental particles like electron, proton and neutrons. Students will also study what isobars, isotopes, atomic numbers, etc is. There are also topics like Pauli's exclusion principle and Hund's rule which are also discussed in this unit.

Unit-3 Classification of Elements and Periodicity in Properties- In this unit students will learn about the history of periodic table and development of the periodic law and the periodic table. Old periodic table or Mendeleev's periodic table was arranged elements based on atomic masses. The modern periodic table arranges the elements based on their atomic numbers. In the periodic table, periodic trends are observed in ionization enthalpies, atomic sizes, electron gain enthalpies, electronegativity and valence.

Unit-4 Chemical Bonding and Molecular Structure- This unit deals with concept like what is ionic bond, what is covalent bond, the polar character of covalent bonds, valence electrons, VSEPR theory, Lewis structure, the concept of hybridization that involves s, d and p orbitals, the molecular orbital theory (MOT) of homonuclear diatomic molecules and more. There are a total of 40 questions in the exercise of the unit.

Unit-5 States of Matter- Matter is existing in 3 physical states- solid, liquid and gas. This unit deals with the two states of matter namely liquid state and gaseous state, the laws governing the behaviour of ideal gases and properties associated with liquids. The important topics of this unit are intermolecular forces, thermal energy, the gaseous state, ideal gas equation, kinetic molecular theory of gases, liquid State and more.

Unit-6 Thermodynamics- Thermodynamics deals with the changes in energy or transfer of energy in physical or chemical processes. This unit talks about the concepts of various systems and different type of systems, surroundings, heat, work, energy and intensive properties and extensive properties and state functions. The first law of thermodynamics, internal energy, enthalpy, the second law of thermodynamics, entropy, Gibbs energy will be discussed.

Unit-7 Equilibrium- In this unit, we will discuss the concept of equilibrium in chemical and physical processes and details about equilibrium's dynamic nature. There are some insights about the equilibrium constant, the law of mass action and what are the factors affecting equilibrium state. Also discuss ionic equilibrium, ionization of bases and acids, weak and strong electrolytes, degree of ionization, the concept of pH and many more.

Unit-8 Redox Reactions- In this unit we will study the concept of reduction and oxidation in detail and various insights about the redox reaction. Also discuss oxidation number, balancing redox reactions, loss and gain of electrons, change in oxidation number and applications of redox reactions. In this unit, there are 30 questions in the exercise.

Unit-9 Hydrogen- Hydrogen is the most abundant element in our universe and the 3rd most abundant element on the surface of the globe.  In this unit, we will learn about hydrogen, its occurrence, its position in the periodic table. And also discuss the isotopes of hydrogen, how they are prepared and its properties. In this unit, there are 36 questions in the exercise.

Unit-10 The s-Block Elements- This unit talks about the s-block elements of the periodic table. In s-block, there is a total of two groups (1&2).  The elements of Group 1 are lithium(Li), sodium(Na), potassium(K), rubidium(Rb), caesium(Cs) and francium(Fr). The elements of Group 2 beryllium(Be), Magnesium(Mg), Calcium(Ca), Strontium(Sr), Barium(Ba) and Radium(Ra). In this unit, we will discuss the properties and preparation of important compounds of that element and also discuss some important trends in detail.

Unit-11 The p-Block Elements- In this unit, students will get to know the general introduction about p-block elements. In the periodic table, p-block elements are arranged in six groups which are 13, 14, 15, 16, 17, and 18. This unit covers only two groups 13 and 14, the rest groups will be covered in the class 12th chapter 7 The p-Block elements. In this unit, there are 38 questions in the exercise.

Unit-12 Organic Chemistry- Some Basic Principles and Techniques- In this unit, we will discuss some basic principles and techniques of analysis which are required for understanding the properties and formation of organic compounds. And also discuss some basic concepts in reactivity and structure of organic compounds, which are formed due to the covalent bonding. In this unit, there is a total of 40 questions in the exercise.

Unit-13 Hydrocarbons- This unit talks about the classification of hydrocarbons, its properties, reactions and use. Hydrocarbon means the compounds of hydrogen and carbon only. Hydrocarbons are an important source of energy. In this unit, we will discuss aliphatic hydrocarbons-alkanes, alkenes and alkynes, their IUPAC nomenclature, chemical reactions, and physical properties.

Unit-14 Environmental Chemistry- This unit focus on environmental chemistry. Environmental chemistry is a branch of chemistry which deals with the chemical change, transport reactions, effects and fates of chemical species in the environment. In this unit, we will discuss environmental pollution related to the water, soil, and air, cause of smog, depletion of the ozone layer, global warming, greenhouse effect, etc. There is a total of 20 questions in the exercise.
