Chemistry is an area of science involved with the properties, structure, and composition of materials, the changes they undergo, and the energy released or consumed throughout these transformations. Every material comprises hundreds of different types of atoms, and have been categorised as elements that can be encountered naturally or man-made.
Because many students consider chemistry to be a complex subject, they do poorly in exams. Students can resolve this issue by reading NCERT solutions for class 12 chemistry, including answers to all chemistry-related topics and issues.
Involvement of Chemistry in our Everyday Life
Every day, thousands of chemical reactions take place around us. Chemical processes drive every human action, from digestion to muscle movement. A few instances of chemistry in everyday life are given below.
- Saponification is a chemical process that is used to make soaps & detergents.
- Emulsification is a chemical reaction used in detergents and soaps to make them more hygienic.
- Plants convert water(H2O), sunlight, and carbon dioxide(CO2) into oxygen and glucose through photosynthesis. This mechanism is the foundation of the entire food cycle.
Chapters in Class 12 Chemistry
The following are some of the most critical topics in Class 12 chemistry.
- Solid-state chemistry – The study of solid-phase compound’s synthesis, structure, and behaviour is known as solid-state chemistry (materials chemistry).
- Solutions – The chapter discusses the characteristics of solutions such as colligative properties, vapour pressure, concentration and so on, plus numerous types of solutions and the usage of mathematical calculations.
- Electrochemistry – Electrochemistry is a discipline of chemistry that studies the flow of electricity and its chemistry.
- Surface chemistry – Surface chemistry is an area of science that examines how different phases of materials interact.
- Chemical kinetics – Students will understand how reactions occur and the rate at which a chemical reaction happens, in this chapter.
- P-Block elements – Students will study the chemistry of elements in the following groups: 15,16,17 and 18. Students will also learn about general patterns in preparation and the characteristics of dinitrogen, phosphorus, chlorine, and other elements.
- D and F block elements – The d-block is made up of elements from groups 3 to 12. The bottom of the table contains the f-block elements divided into two series: lanthanoids and actinoids. Students will study transition elements, including their occurrence and general features, and the synthesis and properties of significant compounds. Electronic configurations, oxidation states, and chemical reactivity of the inner transition metals will also be covered.
- Coordination compounds – Chemical compounds made up of an array of anions or neutral molecules, connected by coordinate covalent bonds to a central atom, are coordination compounds. Coordination compounds are also known as coordination complexes. The molecules or ions that are attached to the central atom are referred to as ligands.
Students should study according to the most critical topics in terms of marks while preparing for the examination. It will aid in understanding several questions from the chapters including Aldehydes, Ketones, Carboxylic acids, Solid-State Chemistry, Biomolecules, Chemical Kinetics, and others.
We can find chemical reactions everywhere. The human body undergoes millions of chemical interactions every day. Many physical activities, including the usage of energy for muscular power, are influenced by chemical processes. As a consequence, chemistry plays an essential role in everyday life.
