Answers: 3

Answers

Dipole -dipole interactions occur when the partial charges formed within one molecule are attracted to an opposite partial charge in a nearby molecule. Polar molecules align so that the positive end of one molecule interacts with the negative end of another molecule.

Answer from: romedome15

Required Answer :- We know that there are certain forces that play in between the molecules in a compound. These forces play a role of binding force i.e. is responsible for keeping the molecule intact. There are also some forces that act between two compounds bringing them together by the means of weak attraction force. They are called the intermolecular forces.

Now let us discuss this interaction.

Dipole-dipole interaction is one of these forces and it is attractive in nature.It is basically the force between the positive end and the negative end of two polar compounds and is responsible for forming a weak attraction between the two polar compounds.Dipole-dipole interaction arises due to partial positive charge on one polar compound which is attracted to the partial negative charge on another molecule of the polar compound.Every polar molecule shows dipole-dipole interaction. For example let’s take hydrochloric acid that is HCl. Here the positive end is the hydrogen atom and it has a partial positive charge and chlorine atom is the negative end and it has a partial negative charge.

δ+ δ− δ+ δ−

δ+ δ− δ+ δ−H - CL H - CL

Additional information :- There are other such forces like London dispersion force, Van der Waals force and even hydrogen bonding. Hydrogen bonding is the strongest intermolecular force. Van der Waals forces are of two types: London dispersion force and dipole- dipole interaction that we have discussed above. London dispersion force is a weaker intermolecular than dipole-dipole interaction.
