Question
The bond length between atoms involved in resonance structures
is exactly the same for all of the same bond in a population of molecules.
changes in length every nanosecond or so, as the molecule switches from one resonance structure to another.
has one preferred position so that in each molecule, one of the bonds is shorter than the other.
has one preferred position so that one bond is shorter than the other; however, which bond is shorter may be different for each molecule, so the average of all resonance bonds in a mole of molecules is the same.
a.is exactly the same for all of the same bond in a population of molecules.
b.changes in length every nanosecond or so, as the molecule switches from one resonance structure to another.
c.has one preferred position so that in each molecule, one of the bonds is shorter than the other.
d.has one preferred position so that one bond is shorter than the other; however, which bond is shorter may be different for each molecule, so the average of all resonance bonds in a mole of molecules is the same.
Explanation / Answer
The bond length between atoms involved in resonance structures has one preferred position so that one bond is shorter than the other; however which bond is shorter may be different for each molecule,so the average of all resonance bonds in a mole of molecules is the same.
Therefore option (d) is correct.
