Question:
The correct order of increasing C–O bond length in CO, CO\(_3^{2-}\), CO\(_2\) is:
The correct order of increasing C–O bond length in CO, CO\(_3^{2-}\), CO\(_2\) is:
Show Hint
Higher bond order means shorter bond length.
Updated On: Mar 24, 2026
- CO < CO\(_2\) < CO\(_3^{2-}\)
- CO\(_2\) < CO\(_3^{2-}\) < CO
- CO < CO\(_3^{2-}\) < CO\(_2\)
- CO\(_3^{2-}\) < CO\(_2\) < CO
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Bond order inversely proportional to bond length.
Step 2: \[ \text{CO (bond order 3)} < \text{CO}_2 \text{ (bond order 2)} < \text{CO}_3^{2-} \text{ (bond order }1\frac{1}{3}) \]
