It's true way true this is so freaken true :)
Hydrogen bonds are a weak chemical bond that is formed when the slightly positive hydrogen atom of a polar covalent bond in on e molecule is attracted to the slightly negative atom of a polar covalent bond in another molecule. Van der Waals interactions (or forces) are weak attractions between molecules or parts of molecules that result from localized charge fluctuations.
The substance is most likely to have Hydrogen bonding between its molecules. There are three major types of intermolecular bonding, which determine the phase of a substance at room temperature (whether its a solid liqiud or gas). Substances which are strongly bonded are more likely to be solids, which substances with very weak bonds are more likely to be gases. Think of the strength of the bond as a glue, the stronger the glue, the more molecules will stick together to be a solid, the weaker the glue, the easier it will be for them to float away as a gas. In order of decreasing strength, these forces are: 1. Atomic Network, or covalent molecular bonding, such as diamond. 2. Ionic bonding, such as sodium chloride. 3. Molecular bonding. This consists of two varietys 3.1 Hydrogen Bonding and 3.2 Van der Waals bonds The first two types of bonding are extremely strong types of bonding, therefore any substance at room temperature with these bonds will definitely be a solid. Substances in which Hydrogen bonds or van der Waals bonds are present are more likely to be liquids and gases. As van der Waals bonds are weaker than Hydrogen bonds, substances with van der Waals bonds are most likely to be gases, while substances which are liquid are most likely to be liquid.
Side bonds link two adjacent chains of atoms in a molecule. The three types of side bonds are hydrogen bonds, salt bonds and disulfide bonds.
Both are intermolecular forces.
Van der Waal's bonds are the weakest of the types of intermolecular bonds.
It's true way true this is so freaken true :)
These forces are: dipole-dipole force, hydrogen bond, induced dipole force and London dispersion force.
These are usually called "van der Waals" bonds. Some of the strongest of these types of bonds occur between hydrogen atoms attached by chemical bonds to a particular other atom in the same molecule but also attracted by electron-rich areas on other molecules in their vicinity, and these are often called "hydrogen bonds."
Two types and they are covalent bond and ionic bond. don't forget Hydrogen bond and London forces.

Strong hydrogen bonds.
Intermolecular forces are strongest in the solid phase. This is because the atoms/molecules are at the closet possible distance without repulsion occurring; the van der Waals contact distance.
