Answer:
Molecular solids are held together by intermolecular forces (IMFs)
EXPLANATION:
Intermolecular forces (IMF) are forces which enhance the interaction between the molecules, like forces of repulsion or attraction that acts between the molecules and other types of particles, e.g., ions or atoms. Intermolecular forces are of three types .They are
- Dipole-Dipole Attraction
- Hydrogen Bonding
- London Dispersion attraction
Dipole-dipole interaction:
The force that occurs when partially oppositely charged ions interacts with the neighbouring molecules
Hydrogen bonding:
It is a special kind of dipole-dipole interaction that takes place in hydrogen atom bonded either to an oxygen, nitrogen, or fluorine atom.
London Dispersion attraction:
This is the weakest among intermolecular forces. This exists between all different types of molecules that are either ionic , covalent-polar or nonpolar.
