Exhibit 1-3
Determine the hybridization for the indicated atoms in each structure below.




11. Refer to Exhibit 1-3. The hybridization of this oxygen atom (A) is ______.

ANS:
sp2


12. Refer to Exhibit 1-3. The hybridization of this oxygen atom (B) is ______.

ANS:
sp3


13. Refer to Exhibit 1-3. The hybridization of this carbon atom (C) is ______.

ANS:
sp3


14. Refer to Exhibit 1-3. The hybridization of this carbon atom (D) is ______.

ANS:
sp


15. The molecular formula C2H4O can be converted into three-line bond (Kekulé) structures that are
consistent with valence rules.




Which one of the Kekulé structures is not consistent with valence rules?
Explain why the structure you chose in part a is not consistent with valence rules.

ANS:
d
The carbon bonded to the oxygen atom in structure d is pentavalent; it has 10 valence
electrons. Carbon can only have eight valence electrons. In addition, the other carbon
has only six valence electrons when it would prefer to have eight.
