A) A 2 X, ΔH vap = 39.6 kJ/mol B) BY 2, ΔH vap = 26.7 kJ/mol C) C 3 X 2, ΔH vap = 36.4 kJ/mol D) DX 2, ΔH vap = 23.3 kJ/mol E) EY 3, ΔH vap = 21.5 kJ/mol List the dominant (strongest) type of IMF for the pure substances, then rank the strength of … The attractive forces between two separate molecules are intermolecular forces. (a). Based on the data in the table above, which of the following liquid substances has the weakest intermolecular forces? Although this molecule does not experience hydrogen bonding, the Lewis electron dot diagram and VSEPR indicate that it is bent, so it has a permanent dipole. In this lab, students will compare and assess the effects of polarity and intermolecular forces of different liquid samples. Out of Ethanol, Water, and Acetone, which substance has the strongest intermolecular forces of attraction? This molecule has an H atom bonded to an O atom, so it will experience hydrogen bonding. The greater the strength of the intermolecular forces, the more likely the substance is to be found in a condensed state; i.e., either a liquid or solid. 3. What about weakest? Then, if Water (H2O) is a liquid at room temperature. 0. solid. dipole-dipole forces hydrogen bonds dipole-dipole forces Questions left blank are not counted against you. A lot of biochemical systems/living systems depend on hydrogen bonding. with different intermolecular forces, as the strength of intermolecular forces increases, the vapor pressure decreases. Which compound most likely has the strongest intermolecular forces? Correspondingly, I2 will have the highest boiling point and F2 will have the lowest boiling point. This test is Rated positive by 89% students preparing for Class 11.This MCQ test is … Chromatography Portfolio 5. February 05, 2021 / By which state of matter has the weakest intermolecular forces Bonding & IMFs Worksheet For the chart below, forces of attraction decrease as you move to the right. As we have seen, the model of an ideal gas assumes that the gas particles . A) Cl2 B) CO C) NaC D) HF E) All of these have intermolecular forces stronger than dispersion. (b). The solid-state has the strongest intermolecular forces of attraction and so their molecules are close to each other. stronger. Which substance below has the strongest intermolecular forces? The most significant intermolecular force for this substance would be dispersion forces. London dispersion forces result from the coulombic interactions between instantaneous dipoles. It is the strongest of all the intermolecular forces and results in some unexpected properties in substances that have it. 18) Based on the following information, which compound has the strongest intermolecular forces? Definitely a solid. This experiment is split into five experiments. Benzene, C6H6 (B) the lower the boiling point. London dispersion forces … Gases. For each of the following pairs of elements, determine whether the compound is ionic, covalent, or metallic. Intermolecular forces, often abbreviated to IMF, are the attractive and repulsive forces that arise between the molecules of a substance. This is most likely due to the fact that 1)I2 2)Br2 3)Cl2 4)F2 5.The strongest Substance ∆Hvap (kJ/mol) Argon (Ar) 6.3 Benzene (C6H6) 31.0 Ethanol (C2H5OH) 39.3 Water (H2O) 40.8 Methane (CH4) 9.2 A They are also known as Van der Waals forces, and there are several types to consider.
