Therefore, the ionic solids become conducting, 1.9. How many of these are tetrahedral voids? Ans: Impurity from group 15 should be added to get n-type semiconductor. Exercise Chapter 1 Class 12 Chemistry THE SOLID STATE Ncert Solutions Question 1:Define the term amorphous. Ferric oxide crystallises in a hexagonal dose- packed array of oxide ions with two out of every three octahedral holes occupied by ferric ions. Extramarks offers NCERT solutions for chapter Solid State of CBSE Class 12. We always try to provide best ncert solutions for class 12 subject Chemistry chapter Chapter 1: THE SOLID STATE. of tetrahedral voids occupied = 2x/3 Sol. To maintain electrical neutrality it occupies one position and thus creates one cation vacancy. Ionic solids, which have anionic vacancies due to metal excess defect, develop colour. The Solid State : NCERT Solutions - Class 12 Chemistry. 1.17. We always try to provide best ncert solutions for class 12 subject Chemistry chapter Chapter 1: THE SOLID STATE. Let’s Take a Look. hcp lattice has the highest packing efficiency. (C.B.S.E. ∴ The formula of the compound = N3M2 or M2N3. Explain with the help of a suitable example. Point Defects – The defects caused by missing or misplaced atoms or ions in the crystal. Class- XII-CBSE-Chemistry The Solid State . This property is shown by those substances whose atoms, ions or molecules contain unpaired electrons, e.g., O2, Cu2+, Fe3+, etc. Why are ionic solids conducting in the molten state and not in the solid-state? Let moles of NaCI = 100 An element with molar mass 2:7 x 10, NCERT Solutions For Class 12 Chemistry The Solid State, NCERT Solutions for Class 10 Science Chapter 1, NCERT Solutions for Class 10 Science Chapter 2, Periodic Classification of Elements Class 10, NCERT Solutions for Class 10 Science Chapter 7, NCERT Solutions for Class 10 Science Chapter 8, NCERT Solutions for Class 10 Science Chapter 9, NCERT Solutions for Class 10 Science Chapter 10, NCERT Solutions for Class 10 Science Chapter 11, NCERT Solutions for Class 10 Science Chapter 12, NCERT Solutions for Class 10 Science Chapter 13, NCERT Solutions for Class 10 Science Chapter 14, NCERT Solutions for Class 10 Science Chapter 15, NCERT Solutions for Class 10 Science Chapter 16, CBSE Previous Year Question Papers Class 12, CBSE Previous Year Question Papers Class 10, Calculations Involving Unit Cell Dimensions. Co-ordination number of atoms P and Q = 8. Unit cell: Each bricks represents the unit cell while the block is similar to the space or crystal lattice. Hello, friends, this video contains a detailed explanation of Solid state intended for upcoming board exams. All the solutions of The Solid State - Chemistry explained in detail by experts to help students prepare for … Give a few examples of amorphous solids. Hence, portion of the atom at the comer that belongs to one unit cell=1/8. Solution: Give a few examples of amorphous solids. Melting points of given substances are following. Sol. Semi-conductors are the substances whose conductivity lies in between those of conductors and insulators. NCERT Solutions for Class 12 Chemistry Book are given below. Ans: (i) An atom at the comer is shared by eight adjacent unit cells. Chapter 1 of Class 12 Chemistry NCERT book deals with topics related to the solid-state. The Chemistry NCERT Solutions Class 12 provides extensive step-by-step solutions to diffcult problmes and equations which prepare students to crack difficulty levels in easiest way. Quartz is the crystalline form of silica (SiO2) in which tetrahedral units SiO4 are linked with each other in such a way that the oxygen atom of one tetrahedron is shared with another Si atom. Amorphous solids do not have a sharp melting point and melt over a range of temperature. Hence, an electron deficient hole is created and therefore, it is a p – type semiconductor. (i) n-type semiconductor: When a silicon or germanium crystal is doped with group 15 element like P or As, the dopant atom forms four covalent bonds like Si or Ge atom but the fifth electron, not used in bonding, becomes delocalised and continues its share towards electrical conduction. Silicon and germanium show this type of behaviour and are called intrinsic semiconductors. In a monoclinic unit cell : Metallic bond may be strong or weak depending upon the number of valence electrons and the size of the kernels.
