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 $F$.
