Study Set Content:
- hydrocarbons with one or more carbon-carbon triple bonds (R-C=CR)
Alkynes
alkenes and alkynes are what kind of hydrocarbons
unsaturated
As a result of the double or triple bond nature, alkenes and alkynes have fewer hydrogen atoms than comparable alkanes with the same number of carbon atoms.
