PPT-Lecture 13: Carboxylic Acids, Esters, Amines and Amides

Book chapter 14 Pages 472511 Carbon atom of a carbonyl group is attached to a hydroxyl group forming a carboxyl group As functional group attached to an alkyl group or an aromatic group IUPAC names. 2. Introduction. The functional group of carboxylic acids consists of a C=O with -OH bonded to the same carbon.. Carboxyl group is usually written -COOH.. Aliphatic acids have an alkyl group bonded to -COOH.. Histamine. Amines. Amides. Amino acid. P. eptides. Comparison of NH. 3. to Amines . 15.1 Amines. pyramidal. VSEPR?. Classification of Amines. Amines are classified by the number of carbons directly bonded to the nitrogen atom: . Chapter 1.7 Amines and Amides • An amine is an organic compound, related to ammonia, that contains a nitrogen atom bonded to one or more alkyl groups on each molecule • An amide i 20-1. Carboxylic acid derivatives undergo substitution reactions via the (often acid- or base-catalyzed) addition-elimination sequence:. The relative reactivities of the substrates follow a consistent order:. 1. Amines and Amides both contain nitrogen (N).. . 2. Amines and Amides.

Functional Groups Reactivity. :. Functional groups play a significant role in increasing organic compound reactivity, by controlling the direction of the reactions..

Denatured alcohol is a useful portable fuel (e.g. for camping stoves) as, unlike LPG, it does not need to be transported in heavy, specialized containers. It is also used as a solvent..
