Question

What is a molecular solid?

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.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

Explanation:

Answer 2

A molecular solid is a type of solid in which molecules are held together by van der Waals forces rather than by ionic or covalent bonds.
