TAILIEUCHUNG - Lecture Organic chemistry - Chapter 17: Aldehydes and ketones

Chapter 17 provides knowledge of aldehydes and ketones. In this chapter, the following content will be discussed: Nomenclature, systematic naming (IUPAC), structure, synthesis, reactions, hydration: geminal diols,.and other contents. | Chapter 17: Aldehydes and Ketones Functional Group: Carbonyl Aldehyde: RCHO, Ketone: RCOR’, 10/5/2014 © Univesity of California 1 Nomenclature The carbonyl group of aldehydes and ketones has priority over all other polar or functions used so far, namely RX, ROH, , , (But not COOH— to be covered later) > In addition: Systematic Naming (IUPAC) Aldehydes Alkane Alkanal. Longest chain starts at -CH=O, which contains C1. Examples: Formaldehyde Acetaldehyde IUPAC-accepted common names Cyclic aldehydes have the ending -carbaldehyde after cycloalkane name. The carbon attached to -CH=O is C1. Examples: The unit as a substituent is called formyl. Cis-2-ethenylcyclo-hexanecarbaldehyde ● ● ● Ketones Alkane Alkanone. Longest chain incorporates carbonyl carbon and is numbered from terminus close to C=O. Cyclic ketones are cycloalkanones; C=O is C1. Examples: 2-Pentanone An aldehyde containing a ketone C=O is called an oxoalkanal. Example: Substituent name: acyl O R O CH3 acetyl, but propanoyl

• Chulalongkorn University in Thailand
• This Small Lab Kit was created as a result of the research project entitled “Chemistry Laboratory Based on Chemical Safety and Pollution Minimization” sponsored by Thai Research Fund (RDG 3 07 2543)
• One of the outcomes of this project is the organic laboratory book entitled “Organic Chemistry Laboratory Based on Chemical Safety and Pollution Minimization” written in Thai by professors from 7 universities in this project
• They compiled
• adjusted and tested the experiments taken from several traditional organic chemistry laboratory books using the prototype of Small Lab Kit
