4.Chemical Bonding and Molecular Structure
medium
Correct decreasing order of bond order of oxygen species in $I$ to $IV$
$(I)$ $Na_2O_2$
$(II)$ $O_2 [AsF_6]$
$(III)$ $CsO_2$
$(IV)$ $O_2$
A
$(II), (III), (IV) , (I)$
B
$(II), (III), (I), (IV)$
C
$(IV) , (III), (II), (I)$
D
$(II), (IV), (III) , (I)$
Solution
$I$ consist of $O_2^{2-}$ $1$
$II$ consist of $O_2^+$ $2.5$
$III$ consist of $O_2^-$ $1.5$
$IV$ $O_2$ $2$
