2. Identify the strongest type of intermolecular forces in acetone, ethanol, water and hexane. (Structures listed on page 15.) Experiment 2 Intermolecular Forces There are three general types of intermolecular forces. All substances exhibit London Dispersion Forces (LDF), and they are generally the weakest of the three types. These London forces are due to the attractions between small, temporary dipoles that arise from the constant, random movement of the electrons in a substance. As molar mass increases, the size of...

Which of the following best describes London dispersion forces. Question 1 options: the intermolecular forces that exist when ions from an ionic compound are attracted to the dipole of polar molecules in a mixture. involves molecular orientations in which the positive end of one dipole is near the negative end of another forces that exist only between molecules that contain hydrogen atoms bonded to highly electronegative atoms such as O, N, F. Interactions between temporary dipoles cause atoms to be...

Which of the following statements regarding the solution process is incorrect? Multiple Choice When a solution is formed from an ionic compound, the anions and cations are evenly distributed throughout the solution When a polar covalent compound dissolves in water, dipole-dipole interactions take place between the water molecules and the solute molecules. A nonpolar compound such as hexane, C6H14, forms London dispersion forces with a nonpolar solute, such as 12 during the solution process. O The solution process is always...
