Hydrogen bonds:
is a type of attractive (dipole-dipole) interaction between an electronegative atom and a hydrogen atom bonded to another electronegative atom. This bond always involves a hydrogen atom. A hydrogen bond tends to be stronger than van der waals forces,but weaker than covalent bond or ionic bonds. |

Definition
| All atoms and molecules exhibit weak, short-range attractions for one another due to van der Waals forces.These forces are responsible for the condensation of gases into liquids and the freezing of liquids into solid. |
