Chapter 8 Quiz Review Sheet
There are 6 MC questions and 2 multi-part free response questions. This will be on a sheet of paper, no bubble
sheet.
Understand the connection between type of bond and properties
1. List 4 properties that bonding affects.
Explain the connection between lattice energy and Coulomb’s Law.
2. The lattice energies of KBr (671 kJ/mol) and CsCl (657 kJ/mol) are nearly equal. What can be
concluded from this observation?
3. Explain why LiF (1030 kJ/mol) has a lower lattice energy than ScN (7547 kJ/mol)
Determine the polarity of bond. Distinguish between ionic, polar covalent and nonpolar covalent bonds
4. How does a nonpolar covalent bond differ from a polar covalent bond? Draw a picture to illustrate your
answer.
5. Determine the type of bond present. (nonpolar covalent, polar covalent or ionic)
a. Se-O
b. H-I
c. Li-F
d. O-H
6. Rank the bonds in question 5 in decreasing polarity (from most polar to least polar)
Determine Hrxn from bond enthalpies. (use bond enthalpy values from your resource packet)
7. C2H4 + H2O2  HOCH2CH2OH
a. Is the reaction endothermic or exothermic
b. Are all the Carbon-Carbon bonds the same strength? Justify your answer.
Write formulas, draw Lewis structures, denote resonance, determine bond order and rank species by bond
strength and/or length.
8. Write the formula for carbon monoxide, carbon dioxide and carbonate ion.
9. Write the Lewis structures for carbon monoxide, carbon dioxide and carbonate ion. Mark resonance
structures.
10. Calculate bond order for carbon monoxide, carbon dioxide and carbonate ion.
11. Rank carbon monoxide, carbon dioxide and carbonate ion in decreasing bond length (from longest to
shortest)
Use the formal charge formula to determine which
Lewis structure is the correct one from a list of
possible choices.
