Question

The average lengths for C$-$O, C$=$O, and C$\equiv$O bonds are 1.43, 1.23, and 1.13 Å, respectively. The carbonate ion, CO$_3$$^{2-}$, has a central carbon atom and three O atoms bonded to the C. All three C$-$O bond lengths in the carbonate ion are equal in length. Based on the Lewis structure of CO$_3$$^{2-}$, what is the most likely value for the C$-$O bond length in CO$_3$$^{2-}$? less than 1.13 Å between 1.13 and 1.23 Å greater than 1.43 Å between 1.23 and 1.43 Å
