Which of the following statements about resonance structures is false?...
Explanation:
Resonance Structures:
- Resonance structures are a way of representing the delocalization of electrons in a molecule or ion.
- They are used when a single Lewis structure cannot accurately represent the bonding in a molecule.
- Resonance structures are not individual, real structures but rather theoretical representations of the possible electron distributions in a molecule.
Differences in Resonance Structures:
- Resonance forms differ only in the placement of their π or non-bonding electrons.
- The actual structure of the molecule is a combination or hybrid of all the resonance structures.
Equivalence of Resonance Structures:
- Different resonance structures of a substance do not have to be equivalent.
- Some resonance structures may contribute more to the overall structure of the molecule than others.
- The more stable resonance structures are typically those where formal charges are minimized and octet rules are obeyed.
Validity of Resonance Structures:
- In valid resonance structures, all atoms from the second row of the periodic table must have an octet of electrons.
- This means that elements like carbon, nitrogen, oxygen, and fluorine follow the octet rule in resonance structures.
Therefore, the false statement among the options provided is that different resonance structures of a substance do not have to be equivalent. In reality, some resonance structures may contribute more significantly to the overall structure of the molecule based on stability considerations.
