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

1.	Which of the following statements are correct about CO_(3)^(2-) ?
Answer» Thehybridisation of central atomis `sp^(3)` Its RESONANCE structrue has cone C-O single bond and two C= O double bonds The average formal CHARGE on each oxygen atomin 0 . 67 units All C-O bond length are equal . Solution :HYBRIDISATION involved is `sp^(2)` . Hence ,(a) is wrong . Resonance structure has both C-O bond of equallength . 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 .
