Functional Groups The atoms of organic molecules exist in common combinations Each combination: > unique chemical properties and reactivity > behaves similarly in every organic molecule 10 million organic compounds exist! Predict how any one of those compounds reacts by analyzing its “functional groups” Functional Group-group of atoms with characteristic chemical behavior no matter what molecule it's in Chemistry of every organic molecule,regardless of size or complexity governed by functional groups
0林人写 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

0林有 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
