1、Functional Groups 官能团(Functional Groups): The atom or group of atoms that defines the structure of a particular family of organic compounds and,at the same time determines their properties Structural features that allow for classification of compounds into families The structural similarities in these compounds lead to chemical similarities ●官能团：有机分子中比较活泼.易发生化学反应的 原子或原子团 ●官能团：赋予有机物一类特征结构并决定其性质的 原子或原子团

Functional Groups It should be noted that the importance of a functional group cannot be overstated. A functional group determines all of the following properties of a molecule: Bonding and shape Chemical reactivity ● Type and strength of intermolecular forces Physical properties Nomenclature

Functional Groups A given functional group behaves in nearly the Double same way in every -bond molecule it is a part of The chemistry of everyo CH2 H2C-CH organic molecule, C-CHa regardless of size and HgC H complexity,is determined Ethylene Menthene by the functional groups it Br contains Bromine added here In the reactions of ethylene and menthene with bromine both CH, H2C-CH molecules react with Br2 in the C-CH3 same way HgC H
