Bond energy
is defined as the energy required to break the bond that holds two adjacent atoms together
in a molecule. This energy is usually expressed on a per mole basis. Bond order
is directly related to
bond energy. 1. There are three types of bonds
illustrated in Table 1. Give an
example of each kind of bond. 2. Using Table 1, what is the
relationship between bond order
and bond type? 3. What is the relationship between
bond order and the number
electrons shared in that bond? 1

4. Rank the bond orders in order of increasing strength. (Note: use <, > symbols when making the
ranking) 5. Using Model 2, consider the hydrogen-
halogen compounds (H—X). a.
What is the bond order for the H—X
compounds? b.
What is the trend of bond energy in
relation to the halogen group? c.
What is the trend of atomic radii for the
halogen group? d.
What trend can you theorized between
atomic radii and bond energy? 6. How does bond length relate to bond energy? 7. Using Table 3, why is the bond order for ethene listed as “2”? SKIP #7

8. How do the calculated bond orders for ethane, ethene, and ethyne compare with the bond orders
predicted by Lewis structures?
SKIP #8
9. Why is the C-C bond order Table 3: Lewis Bond Orders and Calculated Bond Orders (Lewis) for ethene given as a
“2” in Table 3? 10. How do the calculated
bond orders for ethane, ethene,
and ethyne compare to bond
orders predicted by the Lewis
structures? 11. How does the calculated bond order for benzene compare to the bond orders predicted by the Lewis
structures? 3
