It is the reactive part of the molecule and defines the family of organic compounds like alcohols, aldehydes, ketones, acids.", "detailed_description": """ Functional Groups are the heart of organic chemistry. **Key Points:** 1. Definition: Specific group of atoms responsible for characteristic reactions of a compound 2. Same functional group = Same chemical behavior, even in different molecules 3. Named by priority order in IUPAC nomenclature **Important Functional Groups with Formula:** 1. Hydroxyl -OH : Alcohols Ex: Ethanol C2H5OH 2. Carbonyl C=O : Ketones Ex: Propanone CH3COCH3 3. Aldehyde -CHO : Aldehydes Ex: Ethanal CH3CHO 4. Carboxyl -COOH : Carboxylic Acids Ex: Acetic acid CH3COOH 5. Amino -NH2 : Amines Ex: Methylamine CH3NH2 6. Halogen -X : Alkyl Halides Ex: Chloroethane C2H5Cl 7. Ether -O- : Ethers Ex: Dimethyl ether CH3OCH3 **This Chapter covers:** - Structure and properties of each functional group - IUPAC naming based on functional group priority - How functional groups affect physical properties like boiling point, solubility - Reactions specific to each functional group """, "exam_point": "Functional group = atom/group that gives characteristic properties to organic compound. The chemistry of organic compounds is the chemistry of their functional groups." }
