1.	In the anion HCOO^(-) the two carbon-oxygen bonds are founds to be of equal length. What is the reason for it?
Answer» The ANION `HCOO^(-)` has TWO equivalent RESONATING structures The anion is obtained by removal of a proton from the acid molecule Electronic orbitals of carbon atom are hybridised The `C = O` bond is WEAKER than the `C - O` bond Solution :SEE chemical properties of acids
