The correct C - O bond length among CO , CO ₃⁻², CO ₂ is:
Options
- ACO < CO ₃²⁻ < CO ₂
- BCO ₃²⁻ < CO ₂ < CO
- CCO < CO ₂ < CO ₃²⁻
- DCO ₂ < CO ₃²⁻ < CO
Correct answer
C. CO < CO ₂ < CO ₃²⁻
Step-by-step solution
More is the single bond character more will be the bond length. Thus, correct order is CO < CO ₂ < CO ₃⁻⁻ Related Theory Compounds with formal C O triple bonds do not exist except for carbon monoxide, which has a very short, and strong bond (112.8 pm).
