Oxidation-reduction and organometallic compounds (氧化-还原和有机金属化合物） 11.1 Introduction Carbonyl (羰基）compounds are a broad group of compounds that includes aldehydes, ketones, carboxylic acids, and esters

STRUCTURE AND NOMENCLATURE OF PHENOLS Phenol: Compounds that have a hydroxyl group directly attached to a benzene ring For example:

5.1 Isomerism: Constitutionalisomers and Stereoisomers 5.2 Enantiomers and chiral

We shall study other examples of additions to the double bonds of alkenes. We begin with the additions of hydrogen halides, sulfuric acid, water (in the presence of an acid catalyst), and halogens

8.1 Introduction Alkenes are hydrocarbons whose molecules contain the carbon-carbon double bond. Hydrocarbons whose molecules contain the carbon-carbon triple bond are called alkynes

7.1 Introduction 7.2 Homolytic bond dissociation nergies 7.3 The reactions of alkanes with halogens

cycloalkanes General formula CnH2n+2 for alkanes C3H8 CH3CH2CH3 Propane General formula CnH2n for cycloalkanes (环烷烃） CnH2n Cyclopropane
