Answer:
- Alkynes are compounds that contain a carbon-carbon triple bond.
Step-by-step 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.
