For resonance forms of a molecule or ion, __________.
a.one always corresponds to the observed structure
b.all the resonance structures are seen in various proportions
c.the observed structure is an average of the resonance forms
d.the same atoms need not be bonded to each other
e.there cannot be more than two resonance structures for a given species

Respuesta :

Correct answer is
c.the observed structure is an average of the resonance forms.

The option that describe resonance form in the question is

the observed structure is an average of the resonance forms

  • Resonance form can be regarded as a way to give description of  delocalized electrons that is present within certain molecules or within a  polyatomic ions , this is used in a case whereby the bonding cannot be expressed using  single Lewis formula.

  • several contributing structures known as resonance structures is used in representation of the molecule or ion that has delocalized electrons.

  • For every resonance form of a molecule, there will be observed structure, however observed structure Serve as average to the resonance form of the molecule.

  • Resonance structure can appear in more than two form as regards a specie.

  • Resonance form of (Ascorbate)  is attached

Therefore, option C is right.
