Question

write resonating structure of carboxylate anion ​

Answer 1

The negative charge that is left after deprotonation of the carboxyl group is delocalized between the two electronegative oxygen atoms in a resonance structure.

Answer 2

Carboxyl groups are functional groups with a carbon atom double-bonded to an oxygen atom and single bonded to a hydroxyl group. The molecular formula is COOH. Carboxyl groups missing a hydrogen atom are de-protonated and ionized. Ionized carboxyl groups act as acids, require less energy and are more stable.
