Solution

The correct option is B NO3>NO2>NO+2
By finding out the bond order of the molecules, we can predict the bond length order.
For NO+2,
B.O=2
Bond order=No. of bondsNo. of resonating structures,
For NO2,
B.O=32=1.5
For NO3,
B.O=43=1.33
The order of bond order is:
NO+2>NO2>NO3
Bond order1Bond length
Thus, the order of bond length is just reverse.
