自秋不特大对 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
自秋转达对 Functional Groups ■官能团(Functional Groups): The atom or group ofatoms that defines the structure of a particular family oforganic 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 ◼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
自秋特大材 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
