(a)
Interpretation:
It is to be determined if the given pair is not resonance structures of one another.
Concept introduction:
Resonance exists in species for which there are two or more valid Lewis structures. Resonance structures differ only in the placement of their electrons, not their atoms. Resonance stabilization is usually high when the resonance contributors are equivalent. More the number of the resonance contributors, the more is the resonance stabilization.
Answer to Problem 1.75P
The given structures are not resonance structures of one another.
Explanation of Solution
The structures of the given pair are shown below:
The two structures have completely different carbon skeleton. The first one has a six membered ring while the second has a seven membered ring. Since these two structures do not have the same position of the atoms, they cannot be resonance structures.
From the position of atoms and electrons, it is found that the given pair is not resonance structures of one another.
