Hydrogen Question 11
Question 11 - 01 February - Shift 2
$O-O$ bond length in $H_2 O_2$ is $\underline{X}$ than the $O-O$ bond length in $F_2 O_2$. The $O-H$ bond length in $H_2 O_2$ is $\underline{Y}$ than that of the $O-F$ bond in $F_2 O_2$.
Choose the correct option for $\underline{X}$ and $\underline{Y}$ from the given below.
(1) $X$ - shorter, $Y$ - shorter
(2) $X$ - shorter, $Y$ - longer
(3) $X$ - longer, $Y$ - longer
(4) $X$ - longer, $Y$ - shorter

Answer: (4)
Solution:
According to bent rule more electronegative atom occupy less s-characters so bond length increases.
$O-H$ bond will be short than $O-F$ bond due to small size of $H$ than $F$.
