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…
The general gas equation is not applicable to real gases at the all the temperature .and pressure. In order to make it applicable to real gases Van der Waals’ made correction in volume and pressure of the gases and derived an equation known as Van der Waals’ equation. Volume Correction The actual volume of gas…
Ideal Gases These are the gases, which obey gas laws at all temperatures and pressures. No such gas is known. Non-Ideal gases (Real gases) These are the gases, which obey gas laws but only at high temperatures and low pressures. These gases do not obey gas laws at low temperature and high pressure. Under these…
