First off, we should know what each one is;
Covalent bonds are chemical bonds
Ionic Bonds are electrical attraction between two oppositely charged atoms or groups
Van Der Waals Forces are attractions between the molecules and hold them together
So, lets compare them, shall we?Well, we can tell that they are all bonds of some kind or another. And they all have forces attracting them to something else.
Hydrogen bonds are stronger than dipole-dipole and Van der Waals forces.
Hydrogen peroxide has covalent bonds between the atoms. The atoms are held together by those covalent bonds. There are van der Waals and dipole-dipole forces between the molecules.
It's true way true this is so freaken true :)
an ionic bond is formed when one or more electrons are transferred from one atom to another. when molecules are close together a slight attraction can develop between the oppositely charged regions of nearby molecules, known as van der waals forces.
Van der Waals interactions
Hydrogen bonds are stronger than dipole-dipole and Van der Waals forces.
Covalent, ionic, hydrogen, van der Waals forces
Hydrogen peroxide has covalent bonds between the atoms. The atoms are held together by those covalent bonds. There are van der Waals and dipole-dipole forces between the molecules.
Ionic compunds which are crystalline- have ionic bonds. Giant covalent can also be crystalline e.g. diamond and silica- these have covalent bonds. Molecular compounds crystallise - these have covalent bonds and the crystals are held together by van der waals forces. and sometimes by hydrogen bonds.

Covalent or van der Waals' bonding
stong bonds are ionic bonds and covalent bonds and weak bonds are van der waals bonds and hydrogen bonds.
Both are intermolecular forces.
Both are intermolecular forces.
Covalent bonds are the intramolecular forces that hold the hydrogens to the carbon in methane, CH4. The intermolecular forces holding several methane molecules together are London dispersion forces (van der Waals forces).
