English Class 12th Chapter Summary (NCERT) - Study Cbse Notes

Chemistry is one of the essential subjects for board examinations. A wide variety of concepts and questions are included in NCERT 12 th 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. Students studying this are expected to have an edge over their peers in both board examinations as well as other entrance exams. 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 aluminum pontoon boat roof jacket to their wide area of impact. 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.

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. 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.

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.

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. Different blocks of the periodic table are named differently by scientists based on their electronic configuration.

Following those rules, the elements present in group 13 to 18 are class 10th ncert chemistry chapter 2 word p-block elements and have a general configuration ns 2 np 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 4 th period. They are transition elements, between the highly electropositive elements in groups 1 and 2 and the weakly electropositive elements of groups 13 to The f-block elements usually appear as a footnote in the standard column periodic table and contain metals of periods 6 and 7.

A vital topic in the NCERT Chemistry Class 12 PDF, coordination compounds are those compounds which have a metal ion in class 10th ncert chemistry chapter 2 word centre called coordination centre with ions of other elements joined with the centre ion, called as ligands. The bonds between the metallic ion and its ligands are coordinated covalent bonds and is 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.

Two types of hydrocarbons � aliphatic and aromatic � when form bonds with halogen compounds, are called as 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 sp 3 hybridised carbon in alkyl groups, while for aryl groups, they do so with the sp 2 hybridized carbon.

Such compounds are of particular importance and used in various ways in our day to day lives. One of the key topics in organic chemistry, alcohols and aluminum pontoon boat roof jacket are formed when an -OH group, respectively replace hydrogen atoms class 10th ncert chemistry chapter 2 word aliphatic and aromatic hydrocarbons.

Alcohols and phenols find extensive usage in our daily lives and is a major constituent inside the food we eat. Ethers are compounds where the class 10th ncert chemistry chapter 2 word atoms are replaced by an alkoxy R-O or aryloxy Ar-O group. Ethers are used in making fragrances. 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. Like other organic compounds discussed before, amines are those compounds in which the hydrogen atoms in the ammonia NH 3 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 derivates of amines. Amines contain a nitrogen atom and another lone class 10th ncert chemistry chapter 2 word of electrons. The functional group -NH 2 is called the amino group. Even though biology and chemistry are different academic subjects, human bodies are the fusion of both of. 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. The most essential biomolecules inside our bodies are carbohydrates, proteins, fats class 10th ncert chemistry chapter 2 word hormones. 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 product nowadays. 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. Combining all the above chapters, in the end, students should not only see these as formulas, and reactions which they Ncert Solutions Class 10th Chemistry Chapter 3 Log 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.

Life-saving drugs and medicines, cleansing agents, active medicinal drugs, detergents we use and class 10th ncert chemistry chapter 2 word food quality enhancers are some important topics discussed in this chapter.

Besides being the prescribed textbooks for schools across India, the NCERT books also offer additional benefits, in terms of scope, quality and subject matter.
