Question

In $HCO{{O}^{-}}$ , the two carbon-oxygen bonds are found to be of equal length. What is the reason for this?

• A. The anion is obtained by the removal of a proton from the acid molecule
• B. Electronic orbitals of carbon atoms are hybridized
• C. The $C=O$ bond is weaker than $C-O$ bond
• D. The anion $HCO{{O}^{-}}$ has two resonating Structures

Answer 1

Answer: (D)

The anion $HCO{{O}^{-}}$ has two resonating Structures

Answer 2

In $HCO{{O}^{-}}$ , the two carbon oxygen bonds are of equal length because the anion HCOO has two resonating structures.
