Question

Draw out the Lewis structures for H2CO3, HCO3-, and CO32-. Thendetermine the maximum number of equivalent resonance structures foreach species. Note that carbon is the central atom in all threecases. If the molecule contains hydrogen atoms they are attached tooxygen atoms. Only count the best structures. For example, Astructure with really bad formal charges should not becounted.
The molecule H2CO3 has______ equivalent Lewis structures.
The molecule HCO3- has______ equivalent Lewis structures.
The molecule CO32- has______ equivalent Lewis structures
