Alkynesare compounds that contain a carbon-carbon triple bond.
Explanation:
The simplest organic compounds are formed excluseively by carbon and hydrogen. They are named hydrocarbons.
There are 3 main types of hydrocarbons, namely alkanes, alkenes and alkynes.
Alkanes posses only single bonds and have general formula Cₙ H₂ₙ ₊ ₂. E.g.: CH₃ - CH₃ (ethane).
Alkenes have one or more double bonds between pairs of carbon atoms. E.g.: CH₃ - CH = CH₂ (propene).
Alkynes contain one or more triple bonds between pairs of carbon atoms. E.g.: CH ≡ CH (ethyne or acethylene).
Both alkenes and alkynes are named unsaturated hydrocarbons, because they have less hydrogen atoms than they could (if they only hade single bonds), while alkanes are saturated hydrocarbons.
