As the bond order increases, bond length decreases and bond order is highest for NO, i.e. 2.5 and least for NO 3-, i.e. 1.33. So, the order of bond length is NO 3-> NO 2-> N 2 O 4> NO

Q. The correct order of $N - O$ bond lengths in $NO, N O_{2}^{-}, N O_{3}^{-}$ and $N_{2} O_{4}$ is

$N_{2} O_{4} > N O_{2}^{-} > N O_{3}^{-} > NO$

$NO > N O_{3}^{-} > N_{2} O_{4} > N O_{2}^{-}$

$N O_{3}^{-} > N O_{2}^{-} > N_{2} O_{4} > NO$

$NO > N_{2} O_{4} > N O_{2}^{-} > N O_{3}^{-}$

As the bond order increases, bond length decreases and bond order is highest for NO, i.e. $2.5$ and least for $N O_{3}^{-}$ , i.e. $1.33$ .
So, the order of bond length is
$N O_{3}^{-} > N O_{2}^{-} > N_{2} O_{4} > NO$

Q. The correct order of N−O bond lengths in NO,NO2−​,NO3−​ and N2​O4​ is

N2​O4​>NO2−​>NO3−​>NO

NO>NO3−​>N2​O4​>NO2−​

NO3−​>NO2−​>N2​O4​>NO

NO>N2​O4​>NO2−​>NO3−​
