Question

the correct arrangement of the species in the decreasing order of bond length between carbon and oxygen atom​

Answer 1

Answer:

CO3^2- , HCO3- , CO2 , CO..

Explanation:

Since, we know that the bond length depends on the bonds which is if triple bond is present, in which 3 electrons are shared which results in short bond length and then the double bond and at last the single bond which is having longest bond length among the three.

The CO will have least bond length since on drawing its lewis structure we will get a triple bond between the C and O.

So, the order will be CO3^2- , HCO3- , CO2 , CO.

Answer 2

Answer: CO3^2-,HCO2-,CO2,CO
