Question

All the C–O bonds in carbonate ion (co;-)
are equal in length. Explain.
​

Answer 1

Explanation:

Because it performs resonance so because of its resonating property all the bonds have partial double bond character and results into equal bond lengths. Carbonate ion is a symmetric, trigonal planar molecule. All three carbon-oxygen bond distances are about 1.28 Angstroms long.

Extra information :

In CO32− ion, carbon is bonded to three oxygen atoms. It is bonded to two oxygen atoms by double bonds and one with single bond. Bonds are not fixed and show resonance therefore, all C−O bonds are equal in length
