Question

Which of the following is not an example of covalent
solid?​

Answer 1

Silicon carbide is an example of a covalent solid.

• Covalent solids, also called network solids, are solids that are held together by covalent bonds. As such, they have localized electrons (shared between the atoms) and the atoms are arranged in fixed geometries. As a result, the melting point of covalent solids is extremely high

• O2 – oxygen.
• O2 – oxygen.Cl2 – chlorine.
• O2 – oxygen.Cl2 – chlorine.PCl3 – phosphorus trichloride.
• O2 – oxygen.Cl2 – chlorine.PCl3 – phosphorus trichloride.CH3CH2OH – ethanol.
• O2 – oxygen.Cl2 – chlorine.PCl3 – phosphorus trichloride.CH3CH2OH – ethanol.O3 – ozone.
• O2 – oxygen.Cl2 – chlorine.PCl3 – phosphorus trichloride.CH3CH2OH – ethanol.O3 – ozone.H2 – hydrogen.
• O2 – oxygen.Cl2 – chlorine.PCl3 – phosphorus trichloride.CH3CH2OH – ethanol.O3 – ozone.H2 – hydrogen.H2O – water.
• O2 – oxygen.Cl2 – chlorine.PCl3 – phosphorus trichloride.CH3CH2OH – ethanol.O3 – ozone.H2 – hydrogen.H2O – water.HCl – hydrogen chloride.
