Vedclass · Answer

(B) In $H_2O_2$,the $O-O$ bond length is $1.48 \, \mathring{A}$.In $O_2F_2$,due to the high electronegativity of fluorine,the $O-F$ bond has more $p$-character,which according to Bent's Rule,increases the $s$-character in the $O-O$ bond.Greater $s$-character leads to a shorter bond length.Thus,the $O-O$ bond length in $O_2F_2$ is $1.22 \, \mathring{A}$.Therefore,the bond lengths for $H_2O_2$ and $O_2F_2$ are $1.48 \, \mathring{A}$ and $1.22 \, \mathring{A}$ respectively.

$O_2F_2$ is an unstable yellow-orange solid and $H_2O_2$ is a colourless liquid. Both have an $O-O$ bond. The $O-O$ bond length in $H_2O_2$ and $O_2F_2$ respectively is:
