Chapter 2, Problem 1EQ
One Lewis structure for the 2-butenyl cation is
Expert Solution & Answer
Interpretation Introduction
Interpretation:
The resonance structure of the given molecule is to be determined
Concept Introduction:
When the electron distribution of a molecule can be depicted correctly in more than one way using different Lewis structures, the drawings are called resonance structures.
Resonance structures have no discrete existence of their own but, taken in combination, describe the true structure of the molecule.
Answer to Problem 1EQ
The resonance structure of the given molecule is,
Explanation of Solution

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.
