$NO^{+} > NO_2^+ > NO > NO^{-}$ (Bond order)

Vedclass · Answer

(C) Let's analyze each option:$A$: The bond angle in $PX_3$ molecules decreases as the electronegativity of the halogen decreases (or size increases). The correct order is $PF_3 > PCl_3 > PBr_3 > PI_3$. Thus,the given order $PI_3 $B$: Dipole moments are: $H_2O$ $(1.85 \ D)$,$SO_2$ $(1.62 \ D)$,$NH_3$ $(1.47 \ D)$,$NF_3$ $(0.24 \ D)$. The order $H_2O > SO_2 > NH_3 > NF_3$ is correct.$C$: Bond orders are: $NO^+$ $(3)$,$NO_2^+$ $(2)$,$NO$ $(2.5)$,$NO^-$ $(2)$. The order $NO^+ (3) > NO (2.5) > NO_2^+ (2) = NO^- (2)$ is correct. The given order $NO^+ > NO_2^+ > NO > NO^-$ is incorrect.$D$: Paramagnetic nature depends on the number of unpaired electrons: $O_2$ $(2)$,$O_2^+$ $(1)$,$O_2^-$ $(1)$,$O_2^{2-}$ $(0)$. The order $O_2 > O_2^+ = O_2^- > O_2^{2-}$ is correct.

Which of these represents the incorrect order of the mentioned property?
