In the anion HCOO– the two carbonoxygen bonds are found to be of equal length. What is the reason for it?
(a) Electronic orbitals of carbon atom are hybridised.
(b) The C = O bond is weaker than the C – O bond.
(c) The anion HCOO– has two resonating structures.
(d) The anion is obtained by removal of a proton from the acid molecule.
