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
Options
- A1 .22   Å,   1 .48   Å
- B1 .48   Å,   1 .22   Å
- C1 .22   Å,   1 .22   Å
- D1 .48   Å,   1 .48   Å
Correct answer
B. 1 .48   Å,   1 .22   Å
Step-by-step solution
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 .
