London dispersion forces (also known as van der Waals forces) hold molecular solids together. or Intermolecular forces
Hydrogen bonding, dipoles, and London dispersion forces.
Intra-molecular forces are stronger than intermolecular forces because intra-molecular forces act within a molecule to hold its atoms together, such as covalent bonds. Intermolecular forces act between molecules and are generally weaker, like van der Waals forces or hydrogen bonding.
Ionic substances are held together by electrostatic forces of attraction between positively and negatively charged ions, while molecular substances are held together by various types of intermolecular forces such as hydrogen bonding, dipole-dipole interactions, and London dispersion forces. Ionic substances have higher melting and boiling points due to the strong electrostatic forces, while molecular substances typically have lower melting and boiling points as the intermolecular forces are weaker.
Intra-molecular bonding refers to the forces that hold atoms together within a molecule, such as covalent bonds or ionic bonds. Inter-molecular interactions are forces between molecules, like hydrogen bonding or van der Waals forces, which affect the interactions between different molecules in a substance.
forces hold matter together
London dispersion forces (LDF), they are the weakest IMF (compared to dipole-dipole attraction and hydrogen bonding)
forces hold matter together
Hold polar molecules together
The bonds are called covalent molecular bonds.
Within the molecule it is the covalent bonds which hold the atoms together. The facts that the molecule is polar or that the substance is in the solid state are irrelevant. If you were trying to ask what holds the molecules together to make the solid, then it is dipole-dipole forces and van der Waals forces.
Molecular and covalent bonds aren't really the same. It is chemical bonds that hold molecules together. These chemical bonds might be called molecular bonds, and they come in two basic flavors: ionic bonds and covalent bonds. A molecular bond might be covalent, but it might be ionic, and that's the difference.
