ALDEHYDES, KETONES AND CARBOXYLIC ACID

28435 In the anion \(HCOO^-\), the two carbon oxygen bonds are found to be equal length. What is the reason

1 The \(C=O\) are weaker than the \(C-O\) bond
2 The anion is obtained by removal of proton from acid molecules
3 The anion has two equal contributing resonating structure
4 Carbon is present in \(sp^2\) state of hybridisation
