Question

molecular solid are ​

Answer 1

Answer:

A molecular solid is a solid consisting of discrete molecules. The cohesive forces that bind the molecules together are van der Waals forces, dipole-dipole interactions, quadrupole interactions, π-π interactions, hydrogen bonding, halogen bonding, London dispersion forces, and in some molecular solids, coulombic interactions.[3][4][5][6][7][8][9][10] Van der Waals, dipole interactions, quadrupole interactions, π-π interactions, hydrogen bonding, and halogen bonding (2-127 kJ mol−1)[10] are typically much weaker than the forces holding together other solids: metallic (metallic bonding, 400-500 kJ mol−1),[4] ionic (Coulomb’s forces, 700-900 kJ mol−1),[4] and network solids (covalent bonds, 150-900 kJ mol−1).[4][10] Intermolecular interactions, typically do not involve delocalized electrons, unlike metallic and certain covalent bonds. Exceptions are charge-transfer complexes such as the tetrathiafulvane-tetracyanoquinodimethane (TTF-TCNQ), a radical ion salt.[5] These differences in the strength of force (i.e. covalent vs. van der Waals) and electronic characteristics (i.e. delocalized electrons) from other types of solids give rise to the unique mechanical, electronic, and thermal properties of molecular solids.[3][4][5][8]

Answer 2

Answer:

A molecular solid is composed of molecules held together by vander waals forces. Its properties are dictated by weak nature of these intermolecular forces. Molecular solids are soft, often volatile , have low melting temperatures , and are electrical insulators.
