Which of the following statements are correct about CO_(3)^(2-) ?

1.	Which of the following statements are correct about CO_(3)^(2-) ?
Answer» The HYBRIDIZATION of central atom is `sp^(3)` . Its resonance structure has one C - O single BOND and two C = O double bonds. The average FORMAL charge on each oxygen atom is 0.67 units All C - O bond lengths are equal Solution :(C, D) The hybridization of carbon in`CO_(3)^(2-)` is `sp^(2)`. So, (A) is WRONG. Due to resonance all C-O bond lengths are equal. Formal charge on each O-atom = `("Total charge")/("Number of O-atoms") = (-2)/(3) = -0.67 `units. ALI C - O bond lengths are equal as mentioned above.
