Begin by understanding the concept of a functional group in organic chemistry. A functional group is a specific group of atoms within a molecule that is responsible for the characteristic chemical reactions of that molecule.
Recognize that functional groups are key to determining the properties and reactivity of organic compounds. They are the reactive part of the molecule and dictate how the molecule will interact with other substances.
Different functional groups have different chemical behaviors. For example, hydroxyl groups (-OH) are characteristic of alcohols, while carboxyl groups (-COOH) are found in carboxylic acids.
Functional groups are often used to classify organic compounds. For instance, compounds containing an amino group (-NH2) are classified as amines.
In summary, a functional group is not a large molecule, a process, or a type of bond, but rather a specific arrangement of atoms that imparts specific chemical properties to the molecule.
