Identify the strongest intermolecular force present in pure samples of the following substances: Identify the strongest intermolecular force operating in the condensed phases of the following substances. Three Types Of Intermolecular Forces Exist. Stronger intermolecular forces between molecules make it. Various physical and chemical properties of a substance are dependent on this force. Correspondingly, if \(q_1\) and \(q_2\) have the same sign, then the force is negative (i.e., a repulsive interaction). Being in the liquid region which is above 5.11 atm and increasing the temperature enough to boil. INTERmolecular force: force is BETWEEN molecules or formula units Identify the types of intermolecular forces for the following chemical compounds (HINT: Dipole-Dipole, Electrostatic, Hydrogen or London Dispersion) NaCl : ____ ELECTROSTATIC CO2: ___ L.D. Give an explanation in terms of IMF for the following differences in boiling point. Web intermolecular forces are the forces that hold two or more molecules together while a bond is an attractive force between two or more atoms.

Chapter 10. This worksheet helps students practice identifying intramolecular bonds, intermolecular forces for a substance, and identifying how intermolecular forces impact the physical properties of substances. Therefore according to this statement gases will have the higher kinetic energy in comparison to intermolecular forces, solids will gave greater intermolecular forces in comparison to kinetic energy, and liquids are in the middle with kinetic energy less than intermolecular . 5 0 obj The strength of the induced dipole moment, \(\mu_{induced}\), is directly proportional to the strength of the electric field, \(E\) of the permanent moment with a proportionality constant \(\alpha\) called the polarizability.
