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
Functional Groups ■官能团(Functional Groups): The atomor group ofatoms that defines the structure of a particular family of organic compounds and,at the same time determines their properties Structuralfeatures that allow for classification of compounds into families The structuralsimilarities 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 affects or determines all of the following properties of a molecule: ●Bonding and shape Chemical reactivity ● Type and strength of intermolecular forces Physical properties Nomenclature
