What is the strongest type of intermolecular force/interaction between solute and solvent in the following solutions?
a) CH2OCH3(g) (dimethylether, ) in H2O(l)
b) Ne(g) in H2O(l)
c) N2(g) in C4H10(g) (butane gas, )
Question 3
a) The strongest type of intermolecular force/interaction between solute and solvent in CH2OCH3(g) in H2O(l) is hydrogen bonding. The O-H group in water can form hydrogen bonds with the lone pairs on the O atoms in dimethylether, leading to strong attraction between the solute and solvent.
b) The strongest type of intermolecular force/interaction between solute and solvent in Ne(g) in H2O(l) is London dispersion forces. The nonpolar nature of Ne makes it unable to form hydrogen bonds or dipole-dipole interactions with water. However, it can still experience temporary dipole-induced dipole attractions with the polar water molecules due to its electron cloud fluctuations.
c) The strongest type of intermolecular force/interaction between solute and solvent in N2(g) in C4H10(g) is London dispersion forces. Both gases are nonpolar and lack permanent dipole moments, so they can only interact through these weak forces of attraction.
