In the anion H C O O - , the two carbon-oxygen bonds are found to be of equal length. What is the reason for it?

Options

  1. AElectron orbits of carbon atom are hybridised.
  2. BThe C = O bond is weaker than the C - O bond.
  3. CThe anion H C O O - has two resonating structures.
  4. DThe anion is obtained by removal of a proton from the acid molecule.

Correct answer

C. The anion H C O O - has two resonating structures.

Step-by-step solution

In HCOO - anion, two carbon-oxygen bonds are of the same bond length as they involve in resonance.
