At room temperature, `CO_(2)` is a gas while `SiO_(2)` is a solid becauseA. `CO_(2)` is nonpolar but `SiO_(2)` is polarB. `SiO_(2)` has higher molecular mass than `CO_(2)`C. `CO_(2)` has covalent bonds but `SiO_(2)` has ionic bonds between the `Si` and `O` atomsD. None of these. |

Answer» Correct Answer - D `CO_(2)` exists as a discrete molecule due to the formation of double bonds between the `C` and `O` atoms by `p_(pi) - p_(pi)` multiple bonding while silicon, unable to form such bonds with oxygen, has an infinite three - dimensional structure. |
