NCERT Chemistry Class 12 PDF 

Chemistry is one of the essential subjects for board examinations. A wide variety of concepts and questions are included in NCERT 12th chemistry, which we have covered in our respective sections. 

In any NCERT 12 chemistry book, students will find topics such as organic chemistry, acids and bases. Questions are mostly asked from these chapters.

In the Class 12 NCERT chemistry PDF, we have collected all important topics and questions from various sources which we have found relevant. Students studying this are expected to have an edge over their peers in both board examinations as well as other entrance exams. 

Chapter 1: Solid State

Solid State is one of the essential chapters in NCERT Chemistry Class 12 PDF. Solid State Chemistry generally deals with the properties and internal structures of molecules and compounds. Compounds can be divided into many groups based on the concepts of solid-state.

Solid-state chemistry also fuses key concepts with solid-state physics, metallurgy, crystallography and electronics due to their wide area of impact.

In NCERT PDF Class 12 chemistry, concepts like crystalline solids, unit cell dimension and lattice structures have been discussed in detail and emphasized on. 

Chapter 2: Solutions

Another important Class 12 chemistry chapter is solutions. A solution is defined as a homogenous blend which is made by mixing two or more solutes and solvents. The element dissolved is called solute while the medium in which it is dissolved is called the solvent. One of the most universally used solvents is water.

Major topics covered in this chapter include solutions and their types, concentration and solubility of various solids and gases in liquids. As part of the NCERT Chemistry Class 12 PDF and should be studied carefully. 

Chapter 3: Electrochemistry

A favourite topic for most examiners and a crucial chapter in the NCERT Class 12 chemistry textbook, electrochemistry is the conjoined study of electronics and chemistry. It determines if an electric current has been produced due to a chemical reaction and vice versa. Such an electric current is produced when electrons travel to and from between the electrode and the electrolyte. 

Our NCERT Chemistry Class 12 PDF lays specific importance on this topic and should be your one-stop solution when you are revising electrochemistry.

Chapter 4: Chemical Kinetics

Chemical kinetics is the branch of chemistry in which the rates of different chemical reactions are studied. It elaborates on how different experimental conditions such as temperature, reaction medium or usage of catalysts can affect the speed with which reactions usually take place.

While a reaction is taking place, the intermediate states, before the final product which is created, are also studied. 

Many mathematical calculations regarding rate calculation are also highlighted in the Class 12 chemistry NCERT book PDF, which should be practised rigorously by students.

Chapter 5: Surface Chemistry

Surface chemistry, along with surface physics, deals with the chemical and physical changes on the surfaces which results in when two different states of matter come in contact. Solid-liquid interfaces, solid-vacuum interfaces and liquid-gas interfaces are some of the most common areas where research takes place. Applications of surface chemistry are studied as surface engineering.

This is an important chapter in the NCERT Chemistry Class 12 PDF, students should have a brief idea of the adsorption of liquids and gases, which is a common theme in surface chemistry. 

Chapter 6: Isolation of Elements

Our planet’s surface and core contain thousands of elements freely or in the form of ores, which have been discovered by humans since time immemorial. Many elements like gold, silver, carbon and Sulphur are present in the form of ores along with a plethora of other elements, which are then isolated with the help of chemical reactions. 

These forms of element isolation have to be feasible enough to be performed under laboratory conditions. These processes of separation are detailed in the NCERT 12 chemistry PDF and should be studied well. 

Chapter 7: The p-Block Elements

Different blocks of the periodic table are named differently by scientists based on their electronic configuration. Following those rules, the elements present in groups 13 to 18 are called p-block elements and have a general configuration ns2np1-6. All such element groups are vital for NCERT chemistry book 12th. 

P-Block elements contain all three types of elements – metals, nonmetals and metalloids and are the only group to have so. The NCERT Chemistry Class 12 PDF lists the properties of all the elements of p-block of the periodic table. 

Chapter 8: d and f-Block Elements

Similar to p-block elements, d and f-block elements are found in nature and included in the periodic table.

D-block ranges from groups 3 to 12 and starts with the 4th period. They are transition elements, between the highly electropositive elements in groups 1 and 2 and the weakly electropositive elements of groups 13 to 16. 

The f-block elements usually appear as a footnote in the standard 18-column periodic table and contain metals of periods 6 and 7. All of these topics are elaborated in 12th chemistry NCERT PDF. 

Chapter 9: Coordination Compounds

A vital topic in the NCERT Chemistry Class 12 PDF, coordination compounds are those compounds which have a metal ion in their centre (called coordination centre) with ions of other elements joined with the centre ion, called ligands. The bonds between the metallic ion and its ligands are coordinated covalent bonds and are an area of prolonged study.

These complexes can be charged on the whole and also exhibit various unknown and unseen properties which are provided in details in chemistry Class 12 NCERT book PDF. 

Chapter 10: Haloalkanes and Haloarenes

Two types of hydrocarbons – aliphatic and aromatic – when forming bonds with halogen compounds, are called haloalkanes and haloarenes respectively. These halogen ions, due to their strong electronegativity, replace the hydrogen atoms in organic molecules and form such compounds. 

The 12th NCERT chemistry PDF also mentions how the halogen atoms attach to the sp3 hybridised carbon in alkyl groups, while for aryl groups, they do so with the sp2 hybridized carbon. Such compounds are of particular importance and used in various ways in our day to day lives.  

Chapter 11: Alcohols, Phenols and Ethers

One of the key topics in organic chemistry, alcohols and phenols are formed when an -OH group, respectively replace hydrogen atoms in aliphatic and aromatic hydrocarbons. Alcohols and phenols find extensive usage in our daily lives and are a major constituent inside the food we eat. 

The NCERT Chemistry Class 12 PDF mentions all their usages and other reactions involving them. 

Ethers are compounds where the hydrogen atoms are replaced by an alkoxy (R-O) or aryloxy (Ar-O) group. Ethers are used in making fragrances. 

Chapter 12: Aldehydes, Ketones and Carboxylic Acids

The carbonyl group (>C=O) is one of the most important functional groups in organic chemistry. When carbon and hydrogen are attached to the carbonyl group, they are called aldehydes. If two carbon atoms bond with the group, they are known as ketones. And if the group bonds with an -OH group, it is called carboxylic acid.

NCERT chemistry Class 12 part 1 PDF contains all the equations which such compounds take part in along with all of their properties.

Chapter 13: Amines

Like other organic compounds discussed before, amines are those compounds in which the hydrogen atoms in the ammonia (NH3) molecule are replaced by alkyl or aryl groups. Proteins and amino acids, which help in the intricate functioning of our muscles and other body parts, are all derivatives of amines. 

Amines contain a nitrogen atom and another lone pair of electrons. The functional group -NH2 is called the amino group. Reactions involving amines and amides form a significant part in Class 12 NCERT chemistry book PDF. 

Chapter 14: Biomolecules

Even though biology and chemistry are different academic subjects, human bodies are the fusion of both of them. We have thousands of different atoms and molecules inside our body, without which we cannot function. The study of how chemicals shape and help in the efficient working of human bodies is called biochemistry.

In NCERT chemistry Class 12 part 2, biomolecules are a fascinating area of study. The most essential biomolecules inside our bodies are carbohydrates, proteins, fats and hormones.

Chapter 15: Polymers

Polymers make up almost every tangible product which we use in our day to day lives. The most important polymer, plastic, is one of the most widely used products nowadays. The NCERT Chemistry Class 12 PDF mentions how polymers are formed and how they are used universally. 

If we look inside polymer molecules, we will notice repeating units called monomers, which are bound together with the help of covalent bonds. Due to this repeating structure, polymers are macromolecules, with huge molecular mass. These are also mentioned in the 12th NCERT chemistry PDF. 

Chapter 16: Chemistry in Everyday Life

Combining all the above chapters, in the end, students should not only see these as formulas, and reactions which they have to perform in laboratories and write on exam papers, but have a holistic idea of how each of the chapters plays a significant role in forming the world what we see today, everything inside and around us.  

This chapter serves as a conclusion to the whole syllabus in 12th NCERT chemistry book PDF. Life-saving drugs and medicines, cleansing agents, active medicinal drugs, detergents we use and artificial food quality enhancers are some important topics discussed in this chapter.
