Carbon dioxide is gas, while \( \mathrm{SiO}_{2} \) is solid because :
(a) \( \mathrm{CO}_{2} \) is a linear molecule, while \( \mathrm{SiO}_{2} \) is angular
\( \mathrm{P} \)
(b) van der Waals' forces are very strong in \( \mathrm{SiO}_{2} \)
W
(c) \( \mathrm{CO}_{2} \) is covalent, while \( \mathrm{SiO}_{2} \) is ionic
(d) Si cannot form stable bonds with O, hence Si has to form a 3D lattice
