NCERT Class 12 Chemistry Chapter 16
NCERT Solutions for Class 12 Chemistry Chapter 16 – Chemistry in Everyday Life includes all the concepts of this chapter. They give you an in-depth conceptual understanding of the topics and subtopics of this chapter. The main concepts talked about in this chapter are as follows.
- Drugs and Their Classification
This part of the chapter tells you that drugs are the low molecular weight molecules chemical agents which affect human metabolism and cure the targeted ailments when taken in prescribed doses. Chemotherapy is the use of chemicals for therapeutic effect.
This part of the chapter tells you that drugs can be classified on the basis of pharmacological effects, drug action, chemical structure and molecular targets.
- Drug Target Interaction
This part of the Class 12 Chemistry in Everyday Life chapter tells you that drugs interact with the target biological macromolecules such as proteins, lipids, carbohydrates and nucleic acids. Enzymes responsible for biocatalysis are proteins in nature, receptors responsible for the communication system in the body are proteins. Drug target interaction is explained using examples of enzymes and receptors. Drugs are designed to interact with some specific targets so that they do not affect other targets. This minimises the side effects and specifies the drug action.
- Therapeutic Actions of Different Classes of Drugs
This portion of the NCERT CBSE Class 12 Chemistry Chapter 16 teaches you about the main classes of drugs based on their therapeutic action. Antacids are used to counteract the overproduction of acids in the stomach, and an example is a cimetidine.
Here you will also learn that antihistamines compete with histamine molecules stopping its effect in the body. For example, terfenadine. Tranquilisers are neurologically active molecules intercepting the message transfer mechanism from nerve to receptor. Chlordiazepoxide is a tranquiliser.
This chapter tells you how analgesics are used to reduce pain without causing any neurological effect, and these are of two types – non-narcotic and narcotic drugs. Antimicrobials are the drugs which destroy/prevent development or growth of microorganisms such as bacteria, viruses, fungi, other pathogens. Antibiotics are used for either checking the growth (bacteriostatic) or killing (bactericidal) the bacteria.
This chapter further elaborates about how Antiseptics and disinfectants are a class of compounds which are used to kill or check the growth of microorganisms when applied on affected animate surfaces or inanimate surfaces. The same substance can act as both disinfectant and antiseptic in different concentrations. Antifertility drugs are the compounds which are used to control population growth, and an example is norethindrone.
- Chemicals in Food
This part of the CBSE NCERT Class 12 Chemistry Chapter 16 tells you that food additives are added to food in order to preserve them, enhance their appeal, increase their nutritive value, and stabilise them. Artificial sweetening agents are added to make food sweet as an alternative to natural sweeteners which increase calorie intake in the body. Food preservatives are means of preventing spoilage of food and manipulate various mechanisms of actions.
- Cleansing Agents
This part of the NCERT Class 12 Chemistry Chapter 16 tells you that detergents are the chemical compounds used for cleaning purposes. Soaps and synthetic detergents are two types of detergents. Soaps are Na or K salts of long-chain fatty acids are prepared through the process of saponification.
Here you will learn that there are many types of soaps such as toilet soaps, soaps that float on water, transparent soaps, medicated soaps, shaving soaps, and scouring soaps. They are used according to specific requirements.
This part further tells you that synthetic detergents are classified into three main categories, namely, anionic, cationic and non-ionic, with each category having its specific uses. Detergents with the straight chain of hydrocarbons are preferred over the ones with a branched-chain as the latter are non-biodegradable and consequently cause environmental pollution.
