The correct order of increasing C - O bond length CO , CO ₃²⁻, CO ₂ is:
Options
- ACO < CO ₂< CO ₃²⁻
- BCO ₂< CO ₃²⁻< CO
- CCO < CO ₃²⁻< CO ₂
- DCO ₃²⁻< CO ₃< CO
Correct answer
A. CO < CO ₂< CO ₃²⁻
Step-by-step solution
C Ohas lowest bond length due to highest bond order. O = C = O has second lowest bond length due to double bond. has highest has bond length due to lowest bond order which is due to resonance.
