Sika said:molecular solids are bonded intramolecularly by:
1_primary bonds
2_secondary
3_van der waals
4_all of them
I think the answer is primary bond !Quantum Defect said:It might help if you give us (and yourself) some examples of molecular solids. With these examples, think about what kinds of forces/bonding exist between the individual units.
Molecular solids are a type of solid material made up of individual molecules held together by intermolecular forces, rather than a network of atoms like in metallic or ionic solids.
Primary bonds in molecular solids are formed through covalent bonding, where atoms share electrons to form strong bonds between them.
Secondary bonds in molecular solids are weaker bonds that form between molecules through dipole-dipole interactions, hydrogen bonding, or London dispersion forces.
Van Der Waals forces are a type of secondary bond that contributes to the strength and stability of molecular solids. These forces are responsible for holding molecules together and determining their melting point and boiling point.
Yes, molecular solids can exhibit properties of both solids and liquids. At low temperatures, they behave like solids with a fixed shape and volume. However, at higher temperatures, they can exhibit properties of liquids as the intermolecular forces weaken and the molecules are able to move more freely.
