WebThat would put a lone pair and a negative charge on C-1, a positive charge on C-2, and a positive charge on C-3. This is a legitimate resonance contributor, but it is a very minor contributor because: 1. It now has three charges instead of one, and. 2. It puts positive charges on adjacent carbon atoms. WebFormal charge can be used to predict which resonance structures are favoured. Resonance Structures of NO2– Ion In the nitrite ion, the bond lengths of both nitrogen-oxygen bonds are equal. The Lewis dot structures of NO 2– highlight a difference in the bond order of the two N-O bonds.
