EduPoint's video: Imperfections in Solids The Solid State - 12 Chemistry for Class 12 in Hindi

In this Chemistry video in Hindi for Class 12 we explained different imperfections or defects in crystalline solids. This is a topic from the chapter 'The Solid States' for Class 12th Chemistry. In crystalline solids, constituent particles are arranged in a highly ordered repeating pattern. Point defects are the irregularities or deviations from ideal arrangement around a point or an atom in a crystalline substance, whereas the line defects are the irregularities or deviations from ideal arrangement in entire rows of lattice points. Point defects can be classified into three types : (i) stoichiometric defects (ii) impurity defects and (iii) non-stoichiometric defects. (a) Stoichiometric Defects : These are the point defects that do not disturb the stoichiometry of the solid. They are also called intrinsic or thermodynamic defects. Following are the types of stoichiometric defects - (i) Vacancy defects (ii) Interstitial defects (iii) Frenkel defect (iv) Schottky defect (b) Non-stoichiometric defects : These are the point defects that disturb the stoichiometry of the solid. Following are the types of non-stoichiometric defects - (i) Metal Excess Defect (ii) Metal Deficiency Defect 👇👇👇👇👇👇👇👇👇 𝑷𝒍𝒂𝒚𝒍𝒊𝒔𝒕 👇👇👇👇👇👇👇👇👇 🔴 THE SOLID STATE - FULL CHAPTER 🔴 Class 12 - Chemistry https://www.youtube.com/playlist?list=PLW0F47OesfFPAjU1Gn-IYExXLvNAeE7eR 👆👆👆👆👆👆👆👆👆👆👆👆👆👆👆👆👆👆👆👆👆👆👆 Previous videos :- 🔴 The Solid State https://youtu.be/-SKpBwt7J8s 🔴 Types of Crystalline Solids https://youtu.be/ojpwJbQX6KM 🔴 NON POLAR molecular solids and LONDON dispersion forces https://youtu.be/bqlqK-uBW2E 🔴 Polar Molecular Solids and Hydrogen Bonded Molecular Solids https://youtu.be/TdyFSxbqWK8 🔴 Ionic Solids https://youtu.be/2k_qKS38cUs 🔴 Metallic Solids https://youtu.be/U7mlKOuo7P4 🔴 Covalent or Network Solids https://youtu.be/1j4uI9ko1ng 🔴 Unit Cell and Packing Efficiency https://youtu.be/9SNP_LTfDLc 🔴 Calculations involving Unit Cell Dimensions https://youtu.be/7launoj1MiA 🔴 Close Packed Structures https://youtu.be/UXWK_slzVis
