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...

what is the strongest type of intermolecular force between solute and solvent in each solution? a.) Cu (s) in Ag (s) b.) CH3CH3 (g) in CH3CH2CH2NH2 (l) c.) CH3Cl (g) in CH3OCH3 (g) My guess would be: a.) they are 2 different metals that are monotomic ions so...ionic bonding? b.) the first is nonpolar? and second is polar? so....dipole induced dipole? or is the second nonpolar? C.) H-bonding with the O and H? or would it be dipole -dipole because...
