B $NO_2^+<NO_2^-<NO_2$
C $NO_2^-<NO_2^+<NO_2$
D $NO_2^-<NO_2<NO_2^+$

Step-by-Step Verified Solution

We know that higher the number of lone pair of electron on central atom, greater is the lp � lp repulsion between Nitrogen and oxygen atoms. Thus smaller is bond angle. The correct order of bond angle is NO 2 _ < NO 2 < NO 2 +
