NCERT Solutions For Class 12 Chemistry: Chapter Descriptions
Chapter 1 The Solid State: We are mostly surrounded by solids and we use them more often than liquids and gases. What makes a substance solid is the nature of constituent particles and the binding forces operating between them. The study of the structure of solids will help you understand the correlation between structure and properties which n turn will help in discovering new solid materials with desired properties like high-temperature superconductors, biodegradable polymers for packaging, etc. Solids can also be classified as crystalline or amorphous on the basis of the nature of order present in the arrangement of their constituent particles. You will learn more in detail when you go through this chapter and attempt the NCERT Solutions for Class 12 Chemistry.
Chapter 2 Solutions: Solutions are basically homogenous mixtures of two or more components. Solutions are classified as solid, liquid and gaseous solutions. Composition of a solution can be revealed by its concentration. The concentration of a solution is expressed in terms of mole fraction, molarity, molality and in percentages. By the end of this chapter, you must be able to define the laws that bound the Solutions. For example, Solutions which obey Raoult’s law over the entire range of concentration are called ideal solutions. Such laws with derivations will be taught in this chapter with great importance in the main exam.
Chapter 3 Electrochemistry: Electrochemistry is the study of electricity production from chemical reactions and the use of electrical energy to bring about non-spontaneous chemical transformations. The theoretical and theoretical and practical considerations of this chapter are extremely important. You will also know the types of electrochemical cells. A galvanic cell will release the chemical energy when a spontaneous redox reaction is converted into electrical work, whereas in an electrolytic cell, electrical energy is used to carry out a non-spontaneous redox reaction. Some of the important concepts such as Gibbs energy and equilibrium constant will be introduced to the students in this chapter.
Chapter 4 Chemical Kinetics: This chapter will help you understand how chemical reactions occur during which factors such as feasibility, extent, and speed are considered. Along with feasibility and extent, you will also know the parameters such as rate and the factors controlling the rate of a chemical reaction. Kinetic studies are the subject that will help you determine the speed or rate of a chemical reaction but also describe the conditions by which the reaction rates can be altered. The factors such as concentration, temperature, pressure, and catalyst affect the rate of a reaction. As all the parameters are interlinked with one another, it is essential to understand each concept in detail.
Chapter 5 Surface Chemistry: As the name suggests, surface chemistry deals with occurrences at the surfaces or interfaces. You will be introduced to the interfacial phenomenon and its significance. Adsorption and absorption differences along with their mechanism in the physical and chemical state ar explained in this chapter clearly. By the end of Surface Chemistry you will be able to explain adsorption results on the basis of Freundlich adsorption isotherms, the nature of the colloidal state, describe the preparation, properties, and purification of colloids.
Chapter 6 General Principles and Processes of Isolation of Elements: As you have known, metals are required for a variety of purposes. For this, we need their extraction from the minerals in which they are present and from which their extraction is commercially feasible. These minerals are known as ores. Ores of the metal are associated with many impurities. In this chapter, you will come across some of the important terms such as minerals, ores, concentration, benefaction, calcination, roasting, refining, etc. Properties and principles of each term are explained in detail in this chapter.
Chapter 7 The P-block elements: Earlier, you must have learned that the p-block elements are placed in groups 13 to 18 of the periodic table. In this chapter, you will learn the chemistry of the elements of subsequent groups along with other elements such as nitrogen, phosphorus, arsenic, antimony, and bismuth. While going through this chapter, you will be able to identify the shift in the non-metals and metals. Let us look at an example for non-metals and metals. Nitrogen and phosphorus are non-metals whereas bismuth is a metal. Knowing the atomic and physical properties of Group 15 elements will help you identify their roles in our world.
Chapter 8 The d and f Block Elements: As we have acquired a fair idea on the p-block elements, let us now take a closer look at the d and f block elements. The d-block of the periodic table contains the elements of the groups 3-12 in which the d orbitals are progressively filled in each of the four long periods. The elements constituting the f -block are those in which the 4 f and 5 f orbitals are filled in the latter two long periods. Learners will be able to differentiate the general characteristics of the d– and f–block elements. This chapter will also help students describe the properties of the f-block elements and give a comparative account of the lanthanoids and actinoids with respect to their electronic configurations, oxidation states, and chemical behavior.
Chapter 9 Coordination Compounds: In the previous chapter, you must have learned about the complex compounds. Complex compounds are called Coordination compounds as per the modern terminology. The chemistry of coordination compounds is an important and challenging area of modern inorganic chemistry. Coordination compounds are famously known to exhibit medicinal chemistry. For example, Chlorophyll, hemoglobin, and vitamin B12 are coordination compounds of magnesium, iron, and cobalt respectively. A variety of metallurgical processes, industrial catalysts, and analytical reagents involve the use of coordination compounds. You will learn a lot about the coordination compounds in detail.
Chapter 10 Haloalkanes and Haloarenes: The replacement of hydrogen atoms in a hydrocarbon by a halogen atom results in the formation of haloalkane and haloarene. Haloalkanes contain halogen atoms attached to the sp3 hybridized carbon atom of an alkyl group whereas haloarenes contain halogen atom attached to sp2 hybridized carbon atom of an aryl group. Through this chapter, you will be able to identify the haloalkanes and haloarenes as per the IUPAC nomenclature system. You will also be able to describe the reactions involved in the preparation of haloalkanes and haloarenes. Haloalkanes and Haloarenes is the beginning of organic chemistry in Class 12 Chemistry.
Chapter 11 Alcohols, Phenols, and Ethers: You have learned in the previous chapter the replacement of carbon atom with the hydrogen. This chapter will help you learn the chemical properties of the Carbon when replaced with the -OH atom forming Alcohols and Phenols. The sugar we eat, the cotton used for fabrics, the paper we use for writing, are all made up of compounds containing –OH groups. Alcohols and Phenols can be further classified into mono (one), di (two), tri (three), or polyhydric compounds depending on the hydroxyl group. By the end of this chapter, you will be able to correlate the physical properties of Alcohols, Phenols, and Ethers with their structures.
Chapter 12 Aldehydes, Ketones, and Carboxylic Acids: In this chapter, you will learn about the carboxyl compounds i.e., organic compounds containing carbon and oxygen double bonds. In aldehydes, the carbonyl group is bonded to a carbon and hydrogen whereas, in the ketones, it is bonded to two carbon atoms. And the carbonyl group that is bonded to oxygen are known as carboxylic acids. Through this chapter, you will be able to discover the uses of Aldehydes, Ketones and Carboxylic acids. For example, in the chemical industry aldehydes and ketones are used as solvents, reagents, and starting materials for the synthesis of other products.
Chapter 13 Amines: You might have heard about Amines as they occur among proteins, vitamins, alkaloids, and hormones. Amines constitute one of the essential organic compounds as they are used even in manufacturing polymers, dyestuffs, and drugs. Basically, Amines are derived by replacing one or more hydrogen atoms of the ammonia molecule or in simple terms they can be considered as the derivatives of the ammonia. Amines can be further divided into primary, secondary, and tertiary amines. Each of these amines plays an important role in the chemical industry.
Chapter 14 Biomolecules: In this chapter, you will go into the molecular level of the living system. As you know every living system contains the nonliving atoms and molecules in its basic composition. The molecular part of the living system comes under the domain of biochemistry. Living systems are made up of various complex biomolecules like carbohydrates, proteins, nucleic acids, lipids, etc. These biomolecules interact with each other and constitute the molecular logic of life processes. In your previous classes, you might have learned about carbohydrates, proteins, and lipids. In this chapter, you will learn the molecular composition of these complex biomolecules in detail.
Chapter 15 Polymers: In your routine life, you might have heard about the polymers once or twice especially when a vendor trying to sell items such as plastic buckets, cups/saucers, children’s toys, packaging bags, synthetic clothing materials, automobile tires, gears, and seals. Polymers play a crucial part as a backbone of four major types of industries such as plastics, elastomers, fibers, and paints. A polymer is basically a large molecule having great molecular mass also commonly known as macromolecules. The process of formation of polymers from monomers is called polymerization. Candidates reading this chapter will have to provide their attention to every detail as this chapter might contain important questions for main exams.
Chapter 16 Chemistry in Everyday Life: This chapter is the end of NCERT Class 12 Chemistry that deals with the principles of chemistry with respect to the sphere of human life. In fact, all the materials we use in our day to day life such as soaps, detergents, even the toothpaste has an organic composition. Chemistry has a great influence on our lives so much that we come across the chemicals at every single moment. Even our daily activities are controlled by the chemicals.
