ANS-1.Rate of evaporation.Liquid with high
boiling points (those that boil
at very high temperatures) tend to
evaporate more slowly than those with lower
boiling temperatures.
For each of the following pairs of molecules, identify the
dominate intermolecular force, and answer any associated
questions.
a. KNO2, CH3NO2
Which compound do you expect to have the highest melting
point?
b. CH3CH2OH, CH3OCH3
Which compound do you expect to have the highest boiling
point?
c. KF, BrF

pressure?
List the dominant IMF for each molecule:
d. NH3, N2
e. CF4, CCl4
f. HCN, KCN

h....
In the following, identify all types of intermolecular forces
and circle the strongest type of intermolecular
force in each of the following?
CH3CH2NH2
CCl3F
CH3CH2CH2CH2CH3
CH3CH2OH
CHCl3
Rank each substance above from strongest to weakest
intermolecular force. Do not look up these substances' physical
properties...determine the ranking based on general intermolecular
force principles. If you predict an "anomaly" (i.e. a "LDF only"
molecule with greater intermolecular forces than a dipole-dipole or
hydrogen bonding molecule), you must briefly state your reasoning.
Please justify why you put each molecule in its order.
CCl4 BH3
SF4
CH3NH2 CO2
N2O (NNO) CH3OH

Choose the molecule or compound that exhibits
dispersion forces as it's strongest intermolecular force.
*LiCl
