funktsionaalrühmi

Funktsionaalrühmi are specific groups of atoms within a larger molecule that are responsible for the characteristic chemical reactions of that molecule. These groups are often referred to as functional groups in English. The presence and arrangement of functional groups determine the physical and chemical properties of organic compounds. For instance, the hydroxyl group (-OH) is a functional group that characterizes alcohols, giving them properties like solubility in water and the ability to form hydrogen bonds.

Other common functional groups include the carboxyl group (-COOH) found in carboxylic acids, the amino group (-NH2) found in amines, and the carbonyl group (C=O) which is part of aldehydes and ketones. Each of these groups imparts distinct reactivity and properties to the molecules they are part of. Understanding functional groups is fundamental to organic chemistry as it allows chemists to predict how molecules will behave and to design synthetic pathways to create new compounds.

The systematic naming of organic compounds often incorporates the names of the functional groups present. For example, a molecule containing a hydroxyl group might be named as an alcohol, and a molecule with a carboxyl group would be named as a carboxylic acid. The study of functional groups enables the classification of organic compounds into families, simplifying the learning and understanding of organic chemistry. Their predictable reactivity allows for targeted reactions, making them essential tools in chemical synthesis and analysis.
