Q. 1. Which of the following is not true about the ionic solids? (A) Bigger ions form the close packed structure. (B) Smaller ions occupy either the tetrahedral or the octahedral voids depending upon their size. (C) Occupation of all the voids is not necessary. (D) The fraction of octahedral or tetrahedral voids occupied depends upon the radii of the ions occupying the voids. Ans. Option (B) is correct. Explanation: In ionic solids, smaller ions occupy the voids, and this depends on stoichiometry of the compounds not on the radius of ions. Q. 2. Solid A is very hard electrical insulator in solid as well as in molten state and melts at an extremely high temperature. What type of solid is it? (A) Ionic solid (B) Molecular solid (C) Covalent solid (D) Metallic solid Ans. Option (C) is correct. Explanation: Covalent solids are generally hard, act as insulators and melting points of such solids are extremely high. Q. 3. Which of the following is a network solid? (
