NEET2019ChemistryChemical Bonding and Molecular StructureActual
Which of the following statements about CO ₃²⁻ ion is correct?
Options
- AThe C - O bond order is 1.5 .
- BThe formal charge on each oxygen atom is -0.67
- CIt has two C - O single bonds and one C = O double bond.
- DThe hybridization of central atom is s p^3 .
Correct answer
B. The formal charge on each oxygen atom is -0.67
Step-by-step solution
Bond order =4 / 3=1.33 Formal charge =-2 / 3=-0.67 All bonds are equivalent due to resonance and hybridisation of central atom is s p^2 .
