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

Correct Answer: D

Solution :

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