Question

(B) In $H_2O_2$, the $O-O$ bond length is $148 	ext{ pm}$. In $O_2F_2$, the $O-O$ bond length is $121.7 	ext{ pm}$. Since $121.7 	ext{ pm} < 148

Vedclass · Accepted Answer

The $O-O$ bond length in $O_2F_2$ is smaller than in $H_2O_2$.

(B) In $H_2O_2$, the $O-O$ bond length is $148 	ext{ pm}$. In $O_2F_2$, the $O-O$ bond length is $121.7 	ext{ pm}$. Since $121.7 	ext{ pm} < 148 	ext{ pm}$, the $O-O$ bond length in $O_2F_2$ is smaller than in $H_2O_2$ due to the strong electronegativity of fluorine atoms which causes repulsion and bond contraction.
