Section 10.1 / Chapter 9 Reading Assignment
NAME:
First read section 10.1 and then chapter 9!
Section 10.1
What is the difference between
intramolecular bonding and
intermolecular forces?
Condensed states
Intermolecular forces
The change in states for a substance
depend upon what?
Dipole-dipole attraction
How strong are dipole-dipole forces?
Hydrogen bonding
Why does hydrogen bonding have an
important effect on physical
properties?
Explain figure 10.4.
In figure 10.4 why do H2O, HF, and NH3
have unexpectedly high boiling points?
If the interactions between molecules
are strong what can we predict about
the boiling point? Explain.
London dispersion forces
What happens as electrons move
around the nucleus that impact
intermolecular forces?
Instantaneous dipole
What does it mean when we say a
dipole is induced?
Explain table 10.2. Why do we see this
trend?
polarizability
Chapter 9
What are two related problems with
the bonding in methane, CH4?
What are the two conclusions that this
analysis leads to?
What do we do in terms of orbitals to
account for the known structure of
methane?
Hybridization
sp3 hybridization
Summarize the bonding of methane.
Hybrid orbitals
Explain the bonding of ethylene in
terms of hybrid orbitals.
sp2
Sigma bond
Pi bond
What does a double bond always
contain?
sp hybridization
Explain the bonding in carbon dioxide in
terms of hybrid orbitals.
Skip to page 428 – Our curriculum only covers the sp3, sp2, and sp hybrid orbitals.
Molecular orbital model
Molecular orbitals
Bonding molecular orbitals
Antibonding molecular orbitals
Molecular orbital theory describes covalent bonding in a manner that can capture a wider array of systems and
phenomena than the Lewis or VESPR models. Molecular orbital diagrams, showing the correlation between atomic and
molecular orbitals, are a useful qualitative too related to molecular orbital theory. Other aspects of molecular orbital
theory are not part of the course or the AP exam.
Paramagnetism
Diamagnetism
Heteronuclear
Diatomic molecules
Delocalized π bonding
What is the photoelectric effect?
How is PES related to the photoelectric
effect?
How do you calculate the energy of an
electron?
How does PES work? Use figure 9.50
for your explanation.
What is PES useful for studying?
