Problem: Which of the molecules or ions below will have the strongest nitrogen-oxygen bond? NO+, NO2-, NO3-

FREE Expert Solution

We are asked to determine the strongest nitrogen-oxygen bond among NO+NO2- and NO3-


We can use Bond Order to determine the length of a bond. Remember that the higher the bond order, the stronger the bond and therefore, the shorter the bond.


Let us draw the Lewis structures of each and its resonance structures and calculate for the average bond order of an N-O bond in all three molecules or ions. We must take note that the bond order of a molecule is the number of bonds between a pair of atoms. The formula we are going to use is:

Average Bond Order = Number of BondsNumber of Resonance Structures
