The concept of resonance describes molecular structures Question 17 options: that have several different geometric arrangements. that have delocalized bonding. that are formed from hybridized orbitals. that have different molecular formulas. that have electrons resonating.

Respuesta :

The concept of resonance illustrates molecular structure which possess delocalized bonding.  

• The resonating structures are required when a single structure is not adequate to illustrate all the characteristics of a molecule.  

• The number of resonating structures relies on the existence of delocalized bonds or delocalized electrons.  

• For example, benzene exhibits two resonance structures as it possess delocalized bonds while cyclohex-1-ene exhibits no resonance structure as it does not possess delocalized bond.  

Thus, the resonance concept illustrates molecular composition, which possess delocalized bonds.
