$CO < CO^{+}$

Vedclass · Answer

(A) Bond length is inversely proportional to bond order.
$1$. For $CO$ (bond order $3$) and $CO^{+}$ (bond order $2.5$),the bond length order is $CO < CO^{+}$. This is correct.
$2$. For $Si-Si$ and $C-C$,$Si-Si$ bond length is greater due to the larger atomic size of $Si$ compared to $C$.
$3$. For $C=C$ and $C=N$,$C=C$ bond length is greater than $C=N$ due to the smaller atomic radius of $N$ compared to $C$.
$4$. For $H_2O_2$ and $O_2F_2$,the $O-O$ bond length in $H_2O_2$ $(1.48 \ \mathring{A})$ is greater than in $O_2F_2$ $(1.22 \ \mathring{A})$ due to the high electronegativity of $F$ atoms reducing the bond length.
Thus,option $A$ is correct.

Which of the following orders of bond length is correct?
