Question
Water molecules in the atmosphere can form hydrogenbonded
dimers, (H2O)2. The presence of these dimers
is thought to be important in the nucleation of ice crystals
in the atmosphere and in the formation of acid rain.
(a) Using VSEPR theory, draw the structure of a water
dimer, using dashed lines to indicate intermolecular
interactions. (b) What kind of intermolecular forces are
involved in water dimer formation? (c) The Kp for water
dimer formation in the gas phase is 0.050 at 300 K and
0.020 at 350 K. Is water dimer formation endothermic or
exothermic?
