Chapter-wise Brief Introduction of NCERT Solutions for Class 11 Chemistry

Chapter 1 Some Basic Concepts of Chemistry

Brief Intro- Matter is made up of small particles which may be atoms or molecules. As different kinds of matter contain different types of atoms or molecules which have different properties, therefore, different kinds of matter have different properties.

The word Molecules was introduced by the famous Italian Chemist Amedo Avogadro. According to him, a molecule is the smallest particle of an element or a compound that can exist free. A molecule is divisible into its constituent atoms, but an atom is not. Thus a hydrogen molecule consists of two hydrogen atoms. Similarly, molecules of chlorine, oxygen, nitrogen, etc. These are called elementary gases. Their molecule contains two atoms each.

The number of atoms of an element in one molecule of it is called atomicity. The atomicity of the elementary gases is 2. The atomicity of ozone, O3 is 3. Metals and noble gases are monoatomic. thus, we say Na, K, Ag, Ne, He and not Na2, K2, etc.

A mole of atoms is a collection of atoms whose total weight is equal to the gram atomic weight. As an equal number of moles of different elements contain an equal number of atoms.

Chapter 2 Structure of The Atom

Atoms are the basis of chemistry. They are the basis for everything in the Universe. You should start by remembering that matter is composed of atoms. We're going to cover basics like atomic structure and bonding between atoms.

An atom is a basic unit of matter that consists of a dense central nucleus surrounded by a cloud of negatively charged electrons. The atomic nucleus contains a mix of positively charged protons and electrically neutral neutrons. It’s the smallest unit of matter that combines with each other to form different types of compounds.

Chapter 3: Classification of Elements and Periodicity in Properties

The Periodic Table is a systematic arrangement of the elements in such a manner that elements possessing similar characteristics are grouped together. It has been divided into four parts viz, s-block, p-block, d-block, and f-block elements. Elements belonging to s- and p-blocks of the table are known as representative elements.

The s- block elements consist of elements of groups 1, 2, and p-block elements are those 13 to 18 of the Periodic Table. The s-block elements differ markedly from the p-block elements in the following aspects:

1. s-block elements predominantly from ionic compounds whereas the p-block elements exhibit a high degree of covalent character.
2. The s-block elements exhibit their highest oxidation state equal to the group number whereas the p-block elements exhibit their highest oxidation state equal to group number minus ten.
3. The s-block elements act as good reducing agents whereas among the p-block elements the reducing character decreases and the oxidising character increase. For example, alkali metals act as very good reducing agents whereas halogens act as strong oxidising agents.

Chapter 4: Chemical Bonding and Molecular Structure

There are several different theories that explain the electronic structure and shapes of known molecules and attempt to predict the shapes of molecules whose structures are so far unknown. Each theory has its own virtues and shortcomings. None is rigorous. Theories change in the light of new knowledge. If we knew or could prove what a bond was, we would not need theories, which by definition cannot be proved. The value of a theory lies more in its usefulness than in its truth. Being able to predict the shape of a molecule is important. In many cases, all the theories give the correct answers.

Chapter 5: States of Matter

Earth is surrounded by a blanket of air which is a mixture of gases. The study of the gaseous state is also very interesting in the same sense that the physical properties of all gases are very nearly the same. Unlike solids and liquids, all gases behave in the same way with changing conditions, such as temperature and pressure.

Of the three states of matter, the gaseous state is the simplest and shows the greatest uniformity in behavior. The behavior of gases can be described by certain quantitative relationships between mass, pressure, volume, and temperature. These relationships are called gas laws.

Chapter 6: Thermodynamics

One of the most fundamental manifestations of nature is the energy that accompanies all changes and transformations. Such diversified phenomena as the drop of a hammer on a nail, the impinging of sunlight on earth and the growth and reactions of the complex mechanism known as a living being all involve absorption, emission, and redistribution of energy. The most common form in which this energy appears is heating. Besides heat, there is mechanical energy, electrical energy, radiant energy, and chemical energy. As diversified and distinct as these various forms may be at first glance appear, they are, nevertheless, related to one another, and under certain conditions may be transformed from one into the other. A study of this interrelation of the various forms of energy in a system constitutes the subject of thermodynamics.

Chapter 7: Equilibrium

• Reversible processes: Reaction in which the products of the reaction can react with one another under the same conditions of the reaction to give back the reactants e.g. formation of NH₃, HI, SO₃,  etc. do not go to completion.
• Irreversible processes: Those in which the products formed do not react to give back the reactants e.g. 2KClO₃ ® 2KCl + 3O₂. Such processes go to completion e.g. precipitation and the reactions involving the evolution of gases.

Equilibria-Physical

S = L   L = V S = V(Physical)

Where (S): Solid ; (L): Liquid (V): Vapour;

For a pure substance, the temperature at which the solid and liquid phases are at equilibrium at one-atmosphere pressure is called melting point or freezing point. Equilibrium is always dynamic.

A saturated solution is the state of equilibrium between the undissolved and the dissolved solute at a given temperature.

Henry’s law:

The mass of the gas dissolved in a given mass of solvent at a particular temperature is directly proportional to the equilibrium pressure of the gas above the solvent.

Chemical equilibria : CaCO₃ = CaO + CO₂

Chapter 8: Redox Reactions

This chapter helps you to get the balance of the chemical reaction by two methods ion-electron methods and oxidation state methods. One question of balancing is always asked in the exam.

Chapter 9: Hydrogen

Elementary chapter of class 11 chemistry. You will learn about the physical and chemical properties of hydrogen with the elaboration of a few chemical compounds like hydrogen peroxide.

Chapter 10: The S-Block Elements

The s- block elements consist of elements of groups 1, 2, and p-block elements are those 13 to 18 of the Periodic Table. The s-block elements differ markedly from the p-block elements in the following aspects:

1. s-block elements predominantly from ionic compounds whereas the p-block elements exhibit a high degree of covalent character.
2. The s-block elements exhibit their highest oxidation state equal to the group number whereas the p-block elements exhibit their highest oxidation state equal to group number minus ten.
3. The s-block elements act as good reducing agents whereas among the p-block elements the reducing character decreases and the oxidising character increase. For example, alkali metals act as very good reducing agents whereas halogens act as strong oxidising agents.

Chapter 11: The P-Block Elements

and p-block elements, it must be noted that the first member of each of these groups (belonging to either s-or p-block) differs markedly from the other heavier members of the group. This is mainly due to the following reasons:

1. The small size of the first member
2. The high electronegatively and
3. The non-availability of d-orbitals for bonding among the second-period element

Chapter 12 Organic Chemistry: Some Basic Principles and Techniques

IUPAC nomenclature of simple organic compounds (only hydrocarbons, mono-functional, and bi-functional compounds) Inductive and resonance effects on acidity and basicity of acids and bases respectively. Reactive intermediates are produced during homolytic and heterolytic cleavage. Formation, structure, stability, and reactivity of alkyl carbocations and free radicals. Optical isomerism of compounds containing up to two asymmetric centers (R/S and E/Z nomenclature excluded).

Chapter 13: Hydrocarbons

It consists of four chapters alkane, alkenes, alkynes, and electrophilic aromatic substitution. This is one of the most important chapters. This chapter is required in class 12 organic chemistry also.

Chapter 14: Environmental Chemistry

Basic concepts are covered in this chapter read the theory and solved all the questions given in the NCERT textbook exercise.
