CHM247H1 Chapter Notes - Chapter 9: Enyne, Mercury (Element), Alkyne
Document Summary
Alkynes: an introduction to organic synthesis: alkyne: a hydrocarbon that contains a carbon-carbon triple bond, acetylene is a common name for the simplest alkyne h-c c-h. 9. 1 naming alkynes: the suffix yne is used. Numbering begins at the end nearest the triple bond. More than one triple bond are diynes, triynes, and so forth. If it contains a double and triple bond, they are called enynes. Numbering of an enyne chain starts with the end nearer to the first multiple bonds. If there is a choice, a double bond will receive the lower number. 9. 3 reactions of alkynes: addition of hx and x2: a carbon-carbon triple bond results from the interaction of 2 sp-hybridized carbon atoms. They lie at 180 to each other: electrophiles undergo addition reactions with alkynes much as they do with alkenes. Reactions with excess hx leads to a dihalide forming.
