a) i) The compound C₆H₁₀ has the general formula CₙH₂ₙ₋₂, which corresponds to an alkyne. With 6 carbon atoms, it is a hexyne. Name: Hexyne ii) The compound CH₃CHCH₂ has three carbon atoms and a double bond, making it an alkene. Name: Propene b) i) Step I shows a long chain alkane being converted into ethene (CH₂=CH₂), which is a smaller alkene. This process involves breaking down larger hydrocarbon molecules into smaller, more useful ones. Name of process: Cracking ii) To distinguish between ethene (CH₂=CH₂) and ethane (CH₃CH₃), a chemical test for unsaturation can be used. • Add bromine water (orange/brown) to both compounds. • Ethene, being an alkene, will undergo an addition reaction with bromine, causing the bromine water to decolorize (turn colorless). CH_2=CH_2 + Br_2 → CH_2Br-CH_2Br • Ethane, being an alkane, will not react with bromine water under normal conditions, and the orange/brown color will persist.
