1.	Which of the following statements aboutCO_(3)^(2-) ion are correct ?
Answer» The C-O bond order is 1.33 The formal charge on each oxygen atom is 0.67 units It has two C-O single bonds and ONE C=O double bond The HYBRIDIZATION of central atom is `sp^(3)` Solution : Bond order `=(4)/(3) =1.33` Formal charge `=(2)/(3) =0.67` All bonds are equivalent due to resonance . Hence , (c) is wrong . Hybridization of central ATM is`sp^(2)` . Hence (d) is wrong .
