The observation that the N − N bond length in N 2 O is 112 pm and that the N − O bond length is 119 pm to be explained. The elimination of any resonance structure of N 2 O on the basis of formal charge is to be identified. The consistency of this elimination is to be checked with the given observation. Concept introduction: The Lewis structure is also known as dot structure. This structure depicts the bonding between atoms and the lone pairs of electrons if exists. Formal charge is a charge given to an atom with assumption that electrons are shared equally between atoms in all chemical bonds irrespective of their electronegativity. To determine: The rationalization of the observation that the N − N bond length in N 2 O is 112 pm and that the N − O bond length is 119 pm ; if any of the resonance structure of N 2 O can be eliminated on the basis of formal charge; if this elimination is consistent with the given observation.
