7.1: The Nomenclature of Alkynes
Terminal Alkyne: triple bond is at the end of the chain
Internal Alkyne: triple bonds located elsewhere along the chain
*a substituent receives the lowest possible number only if there is no functional group
suffix or if counting from either direction leads to the same number for the
functional group suffix

7.2: How to Name a Compound that has More Than One Functional Group
*when the functional groups are a double bond and a triple bond, the chain containing both
groups is numbered in the direction that produces the name containing the lowest
possible number, regardless of which functional group gets the lower number

Document Summary
Chapter 7: the reactions of alkynes/an introduction to multistep. Alkyne: hydrocarbon that contains a c-c triple bond. Terminal alkyne: triple bond is at the end of the chain. Internal alkyne: triple bonds located elsewhere along the chain. *a substituent receives the lowest possible number only if there is no functional group suffix or if counting from either direction leads to the same number for the functional group suffix. 7. 2: how to name a compound that has more than one functional group. *if there is a tie between a double bond and a triple bond, the double bond gets the lower number. *number the chain so that the lowest possible number is given to the functional group with the higher priority. *a triple bond is composed of a sigma bond and two pi bonds. *internal alkynes are more stable than terminal alkynes (b/c alkyl groups stabilize alkynes)
