False statement about resonance structures
Explanation:
Resonance structures are alternate Lewis structures of a molecule or an ion, which can be drawn by shifting electrons between atoms. These structures are used to explain the delocalization of electrons in a molecule or an ion. There are several rules that we need to follow while drawing resonance structures. Let's discuss each statement given in the question one by one.
Individual resonance structures are imaginary, not real:
This statement is true. Individual resonance structures are hypothetical structures that we draw to explain the electron delocalization in a molecule or an ion. They do not represent the actual structure of the molecule or ion.
Resonance forms differ only in the placement of their Pi- or non-bonding electrons or unpaired electrons:
This statement is also true. Resonance structures represent the same molecule or ion, and they differ only in the placement of their electrons. The position of atoms remains the same in all resonance forms.
Different resonance structures of a substance do not have to be equivalent:
This statement is also true. Resonance structures do not have to be equivalent, and they can have different energies. However, the actual structure of the molecule or ion is a hybrid of all resonance structures, and it has the lowest possible energy.
In valid resonance structures, all atoms from the second row of the periodic table must have an octet of electrons:
This statement is false. In valid resonance structures, all atoms should follow the octet rule, but this rule does not apply to atoms from the third row of the periodic table and beyond. These atoms can have more than eight electrons around them, which is called an expanded octet.
