The order of bond length is
Options
- A( O ₂ < O ₃ < O ₂ ²⁻ )
- B( O ₂ < O ₂ ²⁻ < O ₃ )
- C( O ₂ ²⁻ < O ₃ < O ₂ )
- D( O ₂= O ₂ ²⁻ > O ₃ ).
Correct answer
A. ( O ₂ < O ₃ < O ₂ ²⁻ )
Step-by-step solution
Ozone molecule is V-shaped with ( O - O ) bond length (1.278 Å ). The bond length is intermediate between that for a single bond ( (1.48 Å . ) as in ( . H ₂ O ₂ ) ) and for a double bond (1.21 (Å ) as in ( O ₂ )).
