In organic chemistry, a functional group is a specific group of atoms bonded together within a molecule that gives that molecule its characteristic chemical properties and determines its reactivity and behavior. Functional groups are crucial for understanding the structure and function of organic compounds.

Functional groups often participate in specific chemical reactions or exhibit distinctive physical properties, allowing chemists to predict the behavior of a molecule based on the presence of certain functional groups. These groups typically consist of a series of atoms bound together in a specific arrangement, and they can be classified into different categories based on their functional properties.

Some common examples of functional groups include:

1. Hydroxyl group (-OH): This functional group consists of an oxygen atom bonded to a hydrogen atom and is found in alcohols. It imparts characteristics such as polarity, hydrogen bonding, and the ability to act as a weak acid or base.

2. Carbonyl group (C=O): This functional group consists of a carbon atom double-bonded to an oxygen atom. It is found in various compounds such as aldehydes, ketones, and carboxylic acids. The carbonyl group gives these compounds distinctive properties like reactivity with nucleophiles and the formation of hydrogen bonds.

3. Amino group (-NH2): This functional group consists of a nitrogen atom bonded to two hydrogen atoms. It is found in amines and amino acids and imparts basic properties to these compounds, allowing them to interact with acids and form salts.

4. Carboxyl group (-COOH): This functional group is composed of a carbonyl group and a hydroxyl group. It is found in carboxylic acids and gives them their acidity, allowing them to donate a proton (H+) in a chemical reaction.

5. Phosphate group (-PO4): This functional group consists of a phosphorus atom bonded to four oxygen atoms. It is found in molecules such as nucleotides and ATP, and it plays a crucial role in energy transfer and storage.

Functional groups can also include aromatic rings, halogens, sulfhydryl groups, and many others, each with its unique properties and effects on the overall behavior of a molecule.

Understanding functional groups is fundamental in organic chemistry as it helps chemists predict the reactivity, properties, and behavior of organic compounds based on the presence of specific groupings of atoms. By studying functional groups, chemists can design and synthesize new molecules with desired properties for various applications in medicine, industry, and materials science.
