Intermolecular forces (IMF) are the forces which mediate interaction between molecules, including forces of attraction or repulsion which act between molecules and other types of neighboring particles, . Intermolecular forces are weak relative to intramolecular forces – the forces which hold a molecule together. For example, the covalent bond, involving sharing electron pairs between atoms, is much stronger than the forces present between neighboring molecules.

Ion-dipole forces are the reason that ionic compounds dissolve in polar solvents like water. Electronegativity, in lamens terms, is the strength of attraction of the atom to one electron-or how bad the atom wants an electron within a bond. Flourine has 7 electrons, meaning its only missing one electron (IT REAAALLY wants to fill its shell). It means there are now INTERmolecular forces holding each water molecule together. side note, INTER means between, INTRA means within. Consequently, this makes water very 'strong' in the sense that it takes more energy than expected to advance it to a higher energy state (ie liquid to gas), because not only do you have to overcome (break) the INTRAmolecular covalent bond forces, you also have to break the INTERmolecular forces-which by the way are called hydrogen bonds (not. real bonds).
Intermolecular forces, . forces which exist within same molecule or a polyatomic ion,affect the chemical properties of the substance. Greater the intermolecular forces, higher is the boiling point. The intermolecular forces arises due to following interactions: (1) Dipole- dipole interaction. These forces were proposed by Fritz London in 1930. Hence they are termed as London forces. These forces arise from the motion of the electron. It is believed that at any instant of time, the electron cloud of the molecule may be distorted so that an instantaneous dipole used is produced in which one part of the molecule is slightly more negative than the rest. The instantaneous dipole induce dipole in the neighbouring molecule. These are then attracted to each other exactly in the same way as the permanent dipole.
6 Intermolecular Forces Intermolecular forces are the forces of attraction and repulsion between molecules. Intermolecular forces should not be confused with intramolecular forces, which are the electrostatic forces that hold the atoms of a molecule together (. boiling point, melting point, et. Intermolecular forces are also known as van der Waals forces, named after Johannes van der Waals who first postulated them.
3 Types of Intermolecular Forces. Forces That Determine How Molecules Behave. A dipole is induced when the electron clouds of the molecules are distorted by the attractive and repulsive electrostatic forces. Example: An example of London dispersion force is the interaction between two methyl (-CH3) groups. Example: Another example is the interaction between nitrogen gas (N2) and oxygen gas (O2) molecules. Ion-dipole interaction occurs when an ion encounters a polar molecule. In this case, the charge of the ion determines which part of the molecule attracts and which repels. A cation or positive ion would be attracted to the negative part of a molecule and repelled by the positive part. An anion or negative ion would be attracted to the positive part of a molecule and repelled by the negative part.
Intermolecular Forces Ion-Dipole Forces Attractive forces between an ion and a polar molecule Ion-Dipole Interaction. Intermolecular Forces Dispersion Forces Attractive forces that arise as a result of temporary dipoles induced in atoms or molecules. ion-induced dipole interaction. dipole-induced dipole interaction. Induced Dipoles Interacting With Each Other. Intermolecular Forces Dispersion Forces Continued Polarizability is the ease with which the electron distribution in the atom or molecule can be distorted. Polarizability increases with: greater number of electrons
Intermolecular forces are the forces of attraction or repulsion which act between neighboring particles (atoms, molecules, or ions ). These forces are weak compared to the intramolecular forces, such as the covalent or ionic bonds between atoms in a molecule. Ion-dipole forces: electrostatic interaction involving a partially charged dipole of one molecule and a fully charged ion. Instantaneous dipole-induced dipole forces or London dispersion forces: forces caused by correlated movements of the electrons in interacting molecules, which are the weakest of intermolecular forces and are categorized as van der Waals forces. Like a dipole-induced dipole force, the charge of the ion causes a distortion of the electron cloud in the non-polar molecule, causing a temporary partial charge. The temporary partially charged dipole and the ion are attracted to each other and form a fleeting interaction.
