Vedclass · Answer

$(A)$ To determine the bond length, we look at the bond order and the atomic radii of the atoms involved.$1$. The bond orders are: $N_2$ $(3)$, $O_2$ $(2)$, and $Cl_2$ $(1)$.$2$. Bond length is inversely proportional to bond order for similar atoms, but here we must also consider atomic size.$3$. The atomic radius of $Cl$ $(99 	ext{ pm})$ is significantly larger than that of $N$ $(75 	ext{ pm})$ and $O$ $(73 	ext{ pm})$.$4$. Due to the large atomic size of $Cl$, the $Cl-Cl$ bond length $(199 	ext{ pm})$ is much greater than the $O=O$ bond length $(121 	ext{ pm})$ and the $N \equiv N$ bond length $(110 	ext{ pm})$.$5$. Comparing $O_2$ and $N_2$, $N_2$ has a higher bond order $(3)$ than $O_2$ $(2)$, so $N_2$ has a shorter bond length.$6$. Therefore, the decreasing order of bond length is $Cl_2 > O_2 > N_2$.

Label	Order	Property
$i.$	$NH_3 > H_2O > SO_2$	Bond angle
$ii.$	$H_2O > NH_3 > H_2S$	Dipole moment
$iii.$	$N_2 > O_2 > H_2$	Bond enthalpy
$iv.$	$NO^{+} > O_2 > O_2^{2-}$	Bond order

Which of the following is the correct decreasing order of bond length for $N_2$, $O_2$, and $Cl_2$?
