Alkynes: Linear Triple Bonds
Captions available
The idea
An alkyne contains a carbon-carbon triple bond, each sp-hybridized carbon linear, giving that portion a rigid 180° bond angle.
In practice
Ethyne (acetylene) is fully linear because both its carbons are sp hybridized.
Where people slip
A triple bond's extra pi bond makes it more reactive, not more stable — alkynes react even more readily than alkenes in addition.
