Question

Assertion: The $O-O$ bond length in $H_2{O}_2$ is shorter than that of $O_2{F}_2$.
Reason: $H_2{O}_2$ is an ionic compound.

• A. A and R are false.
• B. Both A and R are true but R is not correct explanation of A.
• C. Both A and R are true and R is the correct explanation of A.
• D. A is true but R is false.

Answer 1

The correct option is A A and R are false.

$O_2{F}_2$ has the similar structure as that of $H_2{O}_2$ but the $O-O$ bond length is shorter in $O_2{F}_2$ than in $H_2{O}_2$. This is due to the high electronegativity of attached F-atoms.
$H_2{O}_2$ is a covalent compound.
