Why does a silicon dioxide (SiO2) molecule, forming a quartz crystal, adopt a tetrahedral geometry rather than a linear one?

💡 Explanation

Tetrahedral geometry in SiO2 arises because silicon atom undergoes sp3 hybridization. This hybridization maximizes bond strength and stability. Therefore, the tetrahedral structure is favored, rather than a linear geometry which would not optimize orbital overlap and lead to a less stable molecule.
