Can you recognize functional groups such as carboxyl amino hydroxyl or OH?

Yes, I can recognize functional groups. The carboxyl group (-COOH) is characterized by a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group (-OH). The amino group (-NH2) consists of a nitrogen atom bonded to two hydrogen atoms and is typically found in amino acids. The hydroxyl group (-OH) features an oxygen atom bonded to a hydrogen atom and is commonly found in alcohols.
