Which of the following statements are correct about `CO_(3)^(2-)` ?A. The hybridisation of central atom is `sp^(3)`B. Its resonance structrue has cone C-O single bond and two C= O double bondsC. The average formal charge on each oxygen atom in 0 . 67 unitsD. All C-O bond length are equal . |

Answer» Correct Answer - C::D Hybridisation involved is `sp^(2)` . Hence ,(a) is wrong . Resonance structure has both C-O bond of equal length . Hence , (b) is wrong. formal charge on each O-atom = `(" Total charge ")/(" No, of O-atoms " ) = (-2)/(3) = -0.67 ` units All C-O bond lengths are equal as mentioned above . |
