PPT-Amine II. Reactions 1 amines are

Brønsted and Lewis bases Amines are basic because they possess a pair of unshared electron create an electron density around the nitrogen atom Amine are more basic than water and less basic than hydroxide ion. 1. Chapter 20. Amines. Ch. . 20. . - . 2. About The Authors. . These PowerPoint Lecture Slides were created and prepared by Professor William Tam and his wife, Dr. Phillis Chang. . . Professor William Tam received his B.Sc. at the University of Hong Kong in 1990 and his Ph.D. at the University of Toronto (Canada) in 1995. He was an NSERC postdoctoral fellow at the Imperial College (UK) and at Harvard University (USA). He joined the Department of Chemistry at the University of Guelph (Ontario, Canada) in 1998 and is currently a Full Professor and Associate Chair in the department. Professor Tam has received several awards in research and teaching, and according to . Amine nomenclature. diisopropylamine. pyrrole. nicotine. histamine. pyrrolidine. Formation of amines. triethylamine. Mechanism for LAH reduction of amides. 1-methylpiperidine. One equivalent . SN2 is faster the more R groups on N. Amines are derivatives of ammonia, NH. 3. . Amines can be classified as primary, secondary or tertiary. . Primary amines . have one carbon attached to the nitrogen atom of the amine group. . Secondary amines . 1. Amines and Amides both contain nitrogen (N).. . 2. Amines and Amides. Classified . as . primary. , . secondary. , or . tertiary. based on the number of alkyl groups attached to the nitrogen atom.. Types of Reactions. Types of Reactions. There are . 9. . main types of reactions we will examine:. Combustion. Substitution. Addition. Halogenation. , . Hydrogenation, . Hydrohalogenation. , Hydration. These end in –amine. There is, however, rather confusingly two ways of using this suffix. The exam board tend to use the common version where the name stem ends in -. yl. . propylamine. . . If there is another priority functional group as well as the amine group then the prefix amino is used.. Amines are derivatives of ammonia molecules that contain a nitrogen atom bonded to one or more alkyl groups on each molecule.. . Many amines have strong, unpleasant odours.. . ex. putrescine. cadaverine. * up to 8 carbon atoms in the main chain, with sides chains limited to a maximum of 2 carbon atoms. * one or more amine groups. Amines contain one or more amino functional group (-NH. 2. ). Naming amines follows the alkane naming conventions, adding ‘amine’ as the suffix.. 3. . Amines can be classified as primary, secondary or tertiary. . Primary amines . have one carbon attached to the nitrogen atom of the amine group. . Secondary amines . have two carbons attached to the nitrogen atom of the amine functional group. . Indigofera tinctoria. .. Learning . Goal . Write the common names for amines; draw the condensed structural formulas when given their names. Classify amines as primary . (1. °. ), . secondary . (. 2. Amines are classified as primary, secondary, or tertiary based upon the number of carbon-containing groups that are attached to the nitrogen atom. Those amine compounds that have only one group attached to the nitrogen atom are primary, while those with two or three groups attached to the nitrogen atom are secondary and tertiary, respectively. Classification of amines. Nomenclature of amines. Physical Properties of amines. Preparation of amines. Reaction of amines. 2. By the end of this chapter the student . will know:. Learning. . Objectives. Amines. may be considered as derivatives of ammonia, NH. 3. , in which . an alkyl or aryl group. has replaced one or more of the . hydrogen. . . Those . amines . that carry only alkyl groups are classified as . Amines are more basic than ammonia due to the presence of unshared electron pair on nitrogen atom. THE ORDER OF BASICITY.
