Q21 / 160 · AP EAMCET 2022 (04 Jul Shift 1) · Chemistry

The number of network solids and ionic solids in the list given below is respectively

H2O(ice), AlN, Cu, CaF2 ,diamond, MgO, CCl4, ZnS, Ag, NaCl, SiO2

  • A
    3,3
  • Correct answer
    B
    3,4
  • C
    4,4
  • D
    4,3

Solution

A wide variety of crystalline solids of non-metals result from the formation of covalent bonds between adjacent atoms throughout the crystal. They are also called giant molecules. Covalent bonds are strong and directional in nature, therefore atoms are held very strongly at their positions.

 AlN, diamond, SiO2 are covalent or network solids

Ions are the constituent particles of ionic solids. Such solids are formed by the three dimensional arrangements of cations and anions bound by strong coulombic (electrostatic) forces.

CaF2 , MgO, ZnS, NaCl are ionic solids.

H2O(ice) &  CCl4 are molecular solids.

Cu, & Ag are metalic solids

 

Hence, the correct answer is option: 'B'.
