Solution

## The correct option is B NO3−>NO2−>NO2+To answer this question, firstly we have to calculate the bond orders. The higher the bond order is, shorter the bond length.Nitrogen atom has 2+5=7 electronsOxygen atom has 2+6=8 electrons Now NO has 6 electrons in the bonding and 1 in the antibonding. NO+2 has 2 electrons lesser than NO; So 6 electrons in the bonding and no electrons in the antibonding.Thus, NO+2,Bond Order=6−02=3For NO−2, Band order=6−32=1.5For NO−3, Band order=6−42=1The order of Band order is :NO−3> NO−2> NO+2Hence the correct option is B.
