PPT-3.6 Amines 3.6 Amines Identify, name systematically, and draw the structural formulae

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.

Amines are classified by the number of carbons directly bonded to the nitrogen atom: . . Datang. 欢. 迎. Vaazhga. Welcome. Professor David Wray. University of Warwick,. United Kingdom. Dr Dahlia . Janan. Universiti. . Pendidikan. Sultan . Idris. , Malaysia. Many thanks for coming to today’s meeting. Objectives. To learn how to work out the percentage composition by weight of a compound. To use percentage composition to work out empirical formulae. Percentage compositions. This means what percentage of each element is present in a compound, and therefore tells you what masses of each element are present in any given mass of a compound. . 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.. A heterocyclic amine is a cyclic organic compound that consists of a ring of five or six atoms, of which one or two are nitrogen atoms.. The aroma of pepper is due to . piperidine. , a heterocyclic amine. 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. 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:. 108 . Chem. Learning Objectives. Chapter ten discusses the . amines and . by the end of this chapter the students will:. . Know the structure . . and classification of amines. . Know the. . naming rules for . 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. . Know what amines are and some reactions of amines. Outcomes:. Identify amines. Explain . the reactions of primary aliphatic amines, using . butylamine. as . an example. , with. : water . to form an alkaline . 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. . Kb= [NH3+] [OH-]/[R-NH2]. Kb= Basicity constant defined as the concentration of product of ionized and unionized form of amine. Generally greater the Kb value higher the basicity.. Greater the presence of .
