Chapter 8 Substitution Reactions of Alkyl Halides

Organic Chemistry 6 th Edition Paula Yurkanis Bruice. Chapter 8 Substitution Reactions of Alkyl Halides. What is a substitution reaction?. The atom or group that is substituted or eliminated in these reactions is called a leaving group. Alkyl halides have relatively good leaving groups.

Alkynes

Alkynes. Introduction. Alkynes contain a triple bond. General formula is C n H 2 n -2 . Two elements of unsaturation for each triple bond. Some reactions are like alkenes: addition and oxidation. Some reactions are specific to alkynes. Nomenclature: IUPAC.

Part 3iv Substitution Reactions: Nucleophile

Part 3iv Substitution Reactions: Nucleophile. There is some correlation between basicity and nucleophilicity. remember both a base (B:) and a nucleophile (Nu:) are electronically very similar. Both have a lone pair of electrons on an atom within the molecule. Content of Part 3iv.
