Hello, need help w/vapor pressure problem!

The graph of vapor pressure vs. temperature for three liquids, trichloromethane,
tetrachloromethane and water, are shown below.

Temporature (°C)
Estimate the temperatures at which the vapor pressure of CC14 is
700. torr. (The dash lines are for your reference.) Use these values to calculate
the enthalpy of vaporization, AHvap, of CCl4.
Using information provided in the graph, rank the overall strength of
intermolecular forces in the three liquids, from the weakest to the strongest.
Describe how you know.
What intermolecular forces are present in liquid CHCI; and in liquid CCl,?
Describe how you know from the molecular structural level.
torr and
electronegativity ofC = 2.5, CI = 3.0. C-H bond is considered nonpolar.
