The correct order of \(\mathrm{O}-\mathrm{O}\) bond length in \(\mathrm{O}_{2}, \mathrm{H}_{2} \mathrm{O}_{2}\) and \(\mathrm{O}_{3}\) is
- A \(\mathrm{O}_{2}>\mathrm{O}_{3}>\mathrm{H}_{2} \mathrm{O}_{2}\)
- B \(\mathrm{H}_{2} \mathrm{O}_{2}>\mathrm{O}_{3}>\mathrm{O}_{2}\)
- C \(\mathrm{O}_{3}>\mathrm{O}_{2}>\mathrm{H}_{2} \mathrm{O}_{2}\)
- D \(\mathrm{O}_{3}>\mathrm{H}_{2} \mathrm{O}_{2}>\mathrm{O}_{2}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{H}_{2} \mathrm{O}_{2}>\mathrm{O}_{3}>\mathrm{O}_{2}\)
Step-by-step Solution
Detailed explanation
Correct order of \(O-O\) bond length is \[ \mathrm{H}_{2} \mathrm{O}_{2}>\mathrm{O}_{3}>\mathrm{O}_{2} \] (i) Between \(\mathrm{O}_{3}\) and \(\mathrm{O}_{2}\) \(\because\) Bond order of \(\mathrm{O}_{2}>\mathrm{O}_{3}\) Thus, bond length of \(\mathrm{O}_{3}>\mathrm{O}_{2}\)…
