Alkynes have at least one triple bond in their structure.
The general formula is C(n)H(2n-2).
They are unsaturated.
When naming, specify the positional number of the beginning of the double bond. Try to assign the lowest numbers to the multiple bond. Alkenes get priority over alkynes. If you have to prioritize, the double bond gets priority.
If there is more than one double bond, use di-, tri-, etc.
Alkynes end in -yne suffix.
Naming: double and then triple bonds get priority over alkyl and halogen groups.
Nonpolar. London forces are additive. When comparing, size comes first then packing efficiency.
