Question
Chemistry Question on The solid state
Which of the following is a network solid?
A
SO2 (solid)
B
I2
C
Diamond
D
H2O (ice)
Answer
Diamond
Explanation
Solution
Diamond is a network solid. Thecarbonatoms in diamond are held together by strong covalent bonds, hence it is called as a network solid or covalent network solid.
A network solid is a compound in which all the atoms are bonded by strong covalent bonds forming a continuous network of bonds throughout the solid. Network solids do not contain molecules , they only have covalently bonded atoms. The other options are not correct because:
- SO2 is a molecule not a network solid even though it has covalent bonding.
- I2 is a molecule, so it is also not a network solid.
- H2O (ice) is a ionic solid and a molecule not a network solid.
