Concept explainers
Interpretation: At least four other resonance structures of the given compound have to be drawn and identify the reason for why the given structure is the greatest contributor to overall resonance hybrid.
Concept Introduction:
Resonance is an electron displacement effect for stabilizing a molecule through delocalization of bonding electrons in the pi orbital.
Delocalized electrons stabilize a compound. The extra stability gains from having delocalized electrons are called resonance stabilization or resonance energy.
Bond length: Bond distance or bond length is the average distance between nuclei of two bonded atoms in a molecule. It is a transferable property of a bond between atoms of fixed types
Double bonds: One sigma bond and one pi bond are together known as a double bond.
Bond length is inversely proportional to the bond order.
A higher bond order results in a shorter bond for a given pair of atoms.
