$Si$ cannot form stable $p\pi-p\pi$ multiple bonds with $O$,hence $Si$ forms a $3D$ network structure

Vedclass · Answer

(D) $CO_2$ exists as discrete molecules held together by weak van der Waals' forces,making it a gas at room temperature.In contrast,$Si$ has a larger atomic size and cannot form stable $p\pi-p\pi$ multiple bonds with $O$ atoms.Therefore,$Si$ forms four single covalent bonds with $O$ atoms,resulting in a giant $3D$ covalent network structure,which makes $SiO_2$ a solid.

Carbon dioxide is a gas,while $SiO_2$ is a solid because
