Order of C-O bond length Find the correct order of increasing $\ce{C-O}$ bond length in $\ce{CO}$, $\ce{CO2}$, $\ce{CO3^2-}$.


My solution: as bond length is inversely proportional to the bond order, the order would be $\ce{CO} &lt; \ce{CO2} &lt; \ce{CO3^2-}$. Am I correct?
The order is correct but this is my procedure.
Stronger the bond smaller the length
