Textbook Question
Chapter 2, Problem 9EQ
There are no important resonance structures for the isopropyl cation
because there are no
because, although there are pushable electrons on the oxygen atom, there is no
because the pushable electrons and the receptor are separated by two methylene groups. Thus, the electrons have no way to get to the receptor.

The carbonate anion, CO32- , is a resonance hybrid. Draw all of the important resonance structures for this molecule. If an atom has a nonzero formal charge, be sure the formal charge is shown clearly in the structure. Use the resonance structures to calculate the average formal charge on each O atom (which are all equivalent in the "true" structure). [Note: all of the important contributing resonance structures have octets around each atom that desires an octet.]
An carbon-to-oxygen single bond (i.e. C-O) has a bond energy of 358 kJ/mol and an carbon-to-oxygen double bond (i.e. C=O) has a bond energy of 749 kJ/mol. Estimate the value of the carbon-to-oxygen bond energy in the carbonate anion, CO32— .
Hint: draw the Lewis structure of CO32— , consider resonance and determine which type of bonds it has. Because of the resonance, the bond between C and O will be somewhere in between the single and double bond.
