Liquids are frequently classified according to their physical properties, such as surface tension, vapor pressure, and boiling point. Such classifications are useful when substitutes are needed for a liquid that might not be available.
a) Draw the structure of each of the following compounds: methanol, benzene, pentane, toluene, cyclohexane, 1-butanol, trichloroethylene, acetic acid, acetone, chloroform.
b) Identify the most important kind of intermolecular interaction in each.
c) Sort the compounds into three groups with similar characteristics.
d) If you need a substitute for trimethylpentane, from which group would you make your selection?
