  • Question
  • Which of the Following is an Amorphous solid?


  • Options
  • A. Quartz Glass(Sio2)
  • B. Chrome Alum
  • C. Silicon Carbide(SiC)
  • D. Graphite

  • Correct Answer
  • Quartz Glass(Sio2) 

    Explanation

    An amorphous or non-crystalline solid is a solid that lacks the long-range order that is characteristic of a crystal. In Brief, An amorphous solid is any noncrystalline solid in which the atoms and molecules are not organized in a definite lattice pattern. Such solids include glass, plastic, and gel.

    Quartz glass (SiO2) is an amorphous solid due to its short range order of constituent particles. Note Quartz is a crystalline solid while quartz glass is an amorphous solid.
