The solid consists of discrete chemical species held together by intermolecular forces that are electrostatic or Coulombic in nature. ln CO2 is bonded to 2 Oxygen atoms through double bond O=C=O due to which CO2 exist as discrete molecule. Click to see full answer Similarly one may ask, why is co2 a molecular solid? Here in CO2, both Oxygen atoms form sigma bonds with the central carbon atom and complete their octet. Carbon dioxide, CO2, in the form of dry ice would be classified asA. Solid carbon dioxide undergoes a radical change from a molecular solid to a non-molecular “polymeric” state at elevated pressures and temperatures [1]. Molecular solids are made up of molecules, groups of atoms sharing electrons with each other. A. Thus Ge is probably a covalent solid. It is a small molecule and non-polar with only weak bonds between the molecules. Comparing Ionic and Molecular Compound Intermolecular Forces The force that holds ions together in ionic compounds is a very strong overall attraction between positive and negative charges. A (molecular solid) is a solid composed of individual molecules held together by "van der Waals forces" Essentially being held together by the sum attraction and repulsion between atoms, molecules and surfaces.
