The presence of these partial charges causes the negative dipole to line up next to the positive dipole, thus forming a dipole-dipole interaction. As mentioned earlier in this lesson, certain types of intermolecular forces develop when there are differences in the sharing of electrons within the covalent bonds between atoms. The hydrogen atoms are attracted to one of the lone pairs of electrons on a neighbouring water molecule. For example when two molecules approach each other the charges are distributed from their usual position in such a way that the average distance between opposite charges in the two molecules is a little smaller than that between like charges. van der Waals forces, relatively weak electric forces that attract neutral molecules to one another in gases, in liquefied and solidified gases, and in almost all organic liquids and solids. OK that i understand. They are generated due to the attraction between two oppositely charged species. There are three main types of intermolecular forces studied by chemists. *Hydrogen bonding is the strongest form of dipole-dipole interaction.*. In other words, gravity acts on an object irrespective of the change in time, which is why it is listed under the category of constant forces. They play a key role in the life of all living beings. Cycling is one of the best examples that demonstrate the existence of a constant force.
