Homologous Series of Alkynes
- A homologous series is a group of organic compounds with the same functional group and similar chemical properties, where each successive member differs by a CH2 unit.
- Alkynes are hydrocarbons that contain at least one carbon-carbon triple bond (-C≡C-).
- The general molecular formula for alkynes is CnH2n-2.
EXPLANATION
- C2H4: This is an alkene (double bond) with the molecular formula CnH2n. It does not belong to the homologous series of alkynes.
- C3H4: This follows the general formula of alkynes (CnH2n-2) and contains a triple bond. It belongs to the homologous series of alkynes.
- C6H6: This is an aromatic compound (benzene) and does not belong to the homologous series of alkynes.
- C2H6: This is an alkane with the molecular formula CnH2n+2. It does not belong to the homologous series of alkynes.
The only compound in the list that belongs to the homologous series of alkynes is C3H4. Therefore, the correct answer is C3H4.
