Question

Which of the following is a network solid?

Options

• SO₂

• SiO₂

• CO₂

• H₂O

Answer 1

SiO₂

Explanation:

\[\ce{SiO2}\] (silicon dioxide) is a network solid because it consists of a continuous three-dimensional network of covalent bonds between silicon and oxygen atoms. In contrast, \[\ce{SO2}\], \[\ce{CO2}\], and \[\ce{H2O}\] are molecular compounds with discrete molecules held together by weak intermolecular forces.
