A solution of benzoic acid in benzene has a freezing point of 3.1 °C and a boiling point of 82.6 °C. (The freezing point of pure benzene is 5.50 °C, and its boiling point is 80.1 °C) The structure of benzoic acid is Benzoic acid, C 6 H 5 CO 2 H What can you conclude about the state of the benzoic acid molecules at the two different temperatures? Recall the discussion of hydrogen bonding in Section 11.3.

4. What is the relationship between a liquid's molecular weight and the strength of
intermolecular bonds (assume the liquid is only compared to other liquids that lo
similar intermolecular bonds)? Use the molecular structures and weights of ethano
and methanol, the types of intra- and inter- molecular bonds they make and the
observations you made of ethanol and methanol in this investigation to support your
answer.
What is different about water's molecular structure that makes water not follow this
relationship when compared to ethanol and methanol?
