Question

Which of the following pair consists of only network solid?

• A. $Si{O}_2,C{O}_2$
• B. Graphite, $S{O}_2$
• C. $P_4{O}_{10},P_4{O}_6$
• D. Diamond , $Si{O}_2$

Answer 1

Answer: (D)

Diamond , $Si{O}_2$

1. A network solid or covalent network solid is a chemical compound (or element) in which the atoms are bonded by covalent bonds in a continuous network extending throughout the material. In a network solid there are no individual molecules, and the entire crystal may be considered a macromolecule.
2. So in Diamond , $Si{O}_2$ atoms are bonded by covalent bonds in a continuous network extending throughout the material. In a network solid there are no individual molecules, and the entire crystal may be considered a macromolecule.
3. Hence option D is correct.
