What is intermolecular interaction?

Answer 1

Answer:

Intermolecular forces are the forces of attraction and repulsion that act between molecules or ions to influence the physical properties of compouds.

intermolecular forces are forces that act between stable molecules or between functional groups of macromolecules.

Answer:

Well the key word is molecule. In a substance like water... There are many water molecules. Water molecules are made up of two hydrogen and one oxygen. When someone says the intermolecular forces they are talking about how each molecules of any substance (in this case "water") interact with each other. Each substance or "thing" that we see has intermolecular forces.

Answer:

The intermolecular forces means how strong the bonding is between each individual molecule. This strength of the bonds determines whether a substance is a solid, liquid, or gas at room temperature.

Intermolecular forces are the forces of attraction between molecules. They include:-

Hydrogen bonding, van der waals forces which includes dipole -dipole interactions, dipole -induced dipole interactions, instantaneous dipole interactions (London dispersion forces)

Intermolecular force - or physical force - is the attraction between molecules. It attracts the molecules to stick together or repulses the molecules to separate them.

Answer 2

In general, intermolecular forces can be divided into several categories. The four prominent types are: Strong ionic attraction Recall lattice energy and its relations to properties of solid. The more ionic, the higher the lattice energy. Examine the following list and see if you can explain the observed values by way of ionic attraction: LiF, 1036; LiI, 737; KF, 821; MgF2, 2957 kJ/mol. Intermediate dipole-dipole forces Substances whose molecules have dipole moment have higher melting point or boiling point than those of similar molecular mass, but their molecules have no dipole moment. Weak London dispersion forces or van der Waal's force These forces alway operate in any substance. The force arisen from induced dipole and the interaction is weaker than the dipole-dipole interaction. In general, the heavier the molecule, the stronger the van der Waal's force of interaction. For example, the boiling points of inert gases increase as their atomic masses increases due to stronger Landon dispersion interactions. Hydrogen bond Certain substances such as H2O, HF, NH3 form hydrogen bonds, and the formation of which affects properties (mp, bp, solubility) of substance. Other compounds containing OH and NH2 groups also form hydrogen bonds. Molecules of many organic compounds such as alcohols, acids, amines, and aminoacids contain these groups, and thus hydrogen bonding plays a important role in biological science. Covalent bonding Covalent is really intramolecular force rather than intermolecular force. It is mentioned here, because some solids are formed due to covalent bonding. For example, in diamond, silicon, quartz etc., the all atoms in the entire crystal are linked together by covalent bonding. These solids are hard, brittle, and have high melting points. Covalent bonding holds atoms tighter than ionic attraction. Metallic bonding Forces between atom in metallic solids belong to another category. Valence electrons in metals are rampant. They are not restricted to certain atoms or bonds. Rather they run freely in the entire solid, providing good conductivity for heat and electric energy. These behaviour of electrons give special properties such as ductility and mechanical strength to metals.

Answer 3

whenever we see a object around us it is a matter may be in any state

this matter is made up of atoms. These atoms have a property to attract each other.

this force of attraction is known as inter molecular force of attraction.

This is highest in solids and lowest in gases

Answer 5

the forces that molecules exert on each other

Answer 6

Intermolecular interactions are when liquids and solids differ from gases in that they are held together by forces that act between the individual molecular units of which they are composed.

Answer 7

Inter molecular forces are only for molecules not for Ionic compounds.

Answer 8

This is a force which is manifested between molecules.
