Vedclass · Answer

(B) $1$. For $NH_3$ and $NF_3$: The dipole moment of $NH_3$ $(1.46 \ D)$ is greater than $NF_3$ $(0.24 \ D)$ because in $NH_3$,the orbital dipole and bond dipoles reinforce each other,whereas in $NF_3$,they oppose each other. Thus,$A$ is incorrect.$2$. For $CO$ and $CO_2$: The bond order of $CO$ is $3$ $(C \equiv O)$,while in $CO_2$,the average bond order is $2$ $(O=C=O)$. Higher bond order implies shorter bond length. Thus,$CO $3$. For $NH_2^-$ and $NH_4^+$: $NH_2^-$ has $sp^3$ hybridization with $2$ lone pairs (bond angle $\approx 104.5^\circ$),while $NH_4^+$ has $sp^3$ hybridization with $0$ lone pairs (bond angle $109.5^\circ$). Thus,$NH_2^- $4$. For $I_3^-$ and $N_3^-$: $I_3^-$ has $3$ lone pairs on the central $I$ atom,while $N_3^-$ has $0$ lone pairs on the central $N$ atom. Thus,$I_3^- > N_3^-$. Option $D$ is incorrect.
