Why is the N2 molecule
much more stable than F2?
16. What forces hold the H20
molecules together in ice?
17. Why does ice float on water, when practically no other solid floats
on its own liquid? Why do solid ammonia and solid hydrogen fluoride
not float on their own liquids, like solid water does?
18. What type of attractive forces exist between water and benzene?
Water and methanol? Water and LiF?
19. Why is water a good solvent for ethanol, or ethyl alcohol, but
not for ethane? Would you expect water to be a better, or worse, solvent
for octanol, CH3-CH2-CH2-CH2-CH2-CH2-CH2-CH2-OH,
than for ethanol?
