Definition: The momentary forces of attraction which are created between and induced dipole is called Instantaneous dipole-induced dipole forces or London Dispersion Forces. Or The forces of attraction between non-polar molecules which are formed polar for an instant are called instantaneous dipole-induced dipole forces or London forces. Explanation: The forces of attraction present among the…
Definition: The forces of attraction between polar molecule and temporarily induced molecule (neutral) are called dipole-induced dipole or Debye forces. Explanation: In certain cases, we have a mixture of substances containing polar and non-polar molecules. The positive end of the polar molecule attracts the mobile electrons of the nearly non-polar molecule. In this way polarity…
Definition: The forces of attraction between ions and the molecule of the polar solvent are called ion-dipole forces. Explanation: Molecules with ionic bonds are soluble in polar solvents. Solvent molecules break the lattice of ionic compounds and ions are set free. Oppositely charged ions are produced by ionic compounds in polar solvents which surrounded by…
The attractive forces between the positive end of one molecule with the negative end of other molecule are called dipole-dipole forces. Explanation: In case of HCl, There is much electronegativity difference between hydrogen and chlorine. Due to this chlorine being more electronegative develops a partial negative charge whereas hydrogen develops partial positive charge. Hence the…
Intermolecular Forces Definition Chemistry: The attractive forces that exist between the individual particles (molecules, atoms or ions) are called intermolecular forces. (Van der Waals’ forces). The physical state of a substance depends on the strength of intermolecular forces. The properties of liquids such as boiling point, heat of vaporization, vapour pressure, surface tension and viscosity…
Distinct state of matter, containing significant number of electrically charged particles to affect its electrical properties and behavior is called PLASMA. Plasma Formation: When more heat is applied, the atoms or molecules may be ionized. The atom loses one electron and develops a net positive charge. It becomes an ion. When gas is heated…
