Problem: Draw the structure of CO32−. Include all lone pairs of electrons and formal charges.

FREE Expert Solution

(1) C is less electronegative → Central atom


(2) The total valence electrons of CO32- are:

          Group          Valence Electrons

C        4A                1 x 4 e- = 4 e-

O        6A                3 x 6 e- = 18 e-

                               + 2 e-

Total: 24 valence e-
