CHEM 2444 Lecture Notes - Lecture 8: Pi Bond, Aldehyde, Alkyne
Document Summary
Chapter 16 16. 1 & 16. 2 (will be on the exam) Reactions of ketones and aldehydes will not be on exam one, only structure and nomenclature. Basic points of chapter: the carbonyl unit is reactive because it is polarized and also contains a weak and reactive pi-bond, you should already know. Cip rules for prioritizing substituents, functional groups, and atoms. Sn2 transition state & mechanistic details of this reaction type. At the end of this chapter, you will know: aldehyde & ketone nomenclature. Nomenclature of difunctional molecules containing carbonyl group and alkenes or alkynes. Aldehyde & ketone nomenclature: a c-o has two additional substituents attached to the carbonyl carbon. Carbon groups or a hydrogen atom: all aldehydes except formaldehyde (2 hydrogen atoms) will have one hydrogen and one carbon group attached to the carbonyl carbon. Cyclic aldehydes suffix is carbaldehyde or carboxaldehyde. Dialdehydes are suffixed -dial: if 2 carbon substituents are attached to the carbonyl carbon, it is a ketone.
