Question 1 (true/false worth 4 points) (03.06 lc) an instantaneous dipole occurs when a molecule's moving electrons are briefly more concentrated in one place than another, causing the molecule to become temporarily polarized.
true false
question 2(multiple choice worth 4 points) (03.06 lc) what type of intermolecular force occurs between all substances?
covalent bonding
hydrogen bonding
ion-dipole force
london dispersion force
question 3(multiple choice worth 4 points) (03.06 mc) when comparing h2, nh3, o2, and ch4, which of the following statements is correct?
ch4 has the highest boiling point because it experiences dipole-dipole forces.
h2 has the strongest intermolecular forces because it has the lowest mass. nh3 has the highest boiling point because it experiences hydrogen bonding.
o2 has the strongest intermolecular force because it experiences london dispersion forces.
question 4(multiple choice worth 4 points) (03.06 mc)
the boiling points of diatomic halogens are compared in the table.
boiling points of diatomic halogens molecule boiling point
f2 −188 °c
cl2 −34 °c
br2 59 °c
i2 184 °c
which of the following statements best explains the trends in boiling points?
the atomic size increases down the group, and this decreases the strength of the intermolecular forces.
the total number of electrons decreases down the group, and this decreases the strength of the intermolecular forces.
the total number of electrons increases down the group, and this increases the strength of the intermolecular forces.
the chances of forming a permanent dipole increase down the group and this increases the strength of the intermolecular forces.
question 5(multiple choice worth 4 points) (03.06 mc) what is the strongest intermolecular force that occurs between molecules of co2?
dipole-dipole
induced dipoles
ionic bonding
london dispersion
