In the anion HCOO– the two carbon-oxygen 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–C bond
C.The anion HCOO– has two resonating structures✓ Correct
D.The anion is obtained by removal of a proton from
Explanation
The anion HCOO– has two resonating structures and due to resonance both carbon-oxygen bonds have partial double bond character.
