ALDEHYDES, KETONES AND CARBOXYLIC ACID

28135 In the anion \(HCO{O^ - }\) the two carbon-oxygen bonds are found to be of equal length. What is the reason for it

1 Electronic orbitals of carbon atom are hybridised
2 The \(C = O\) bond is weaker than the \(C -O\) bond
3 The anion \(HCO{O^ - }\) has two resonating structures
4 The anion is obtained by removal of a proton form the acid molecule
