Q. $O_{2} F_{2}$ is an unstable yellow orange solid and $H_{2} O_{2}$ is colourless liquid. $O - O$ bond length in $H_{2} O_{2}$ and $O_{2} F_{2}$ respectively are

$1.22 \overset{˚}{A}, 1.48 \overset{˚}{A}$

$1.48 \overset{˚}{A}, 1.22 \overset{˚}{A}$

$1.22 \overset{˚}{A}, 1.22 \overset{˚}{A}$

$1.48 \overset{˚}{A}, 1.48 \overset{˚}{A}$

$x_{1} > x_{2}$
According to Bent's rule in $O_{2} F_{2}$ , there is more p-character in $O - F$ bond in comparison to $O - H$ bond in $H_{2} O_{2};$ hence s-character in $O - O$ bond is greater in $O_{2} F_{2}$ so bond length is smaller in this.
