Remember! Alkenes are Unsaturated Hydrocarbons!

  • Definition: Alkenes contain a carbon-carbon double bond (C=C).
  • Why are they special?: The C=C bond is an electron-rich area, making alkenes more reactive than their single bonded pals, alkanes.

🚀 Real-World Analogy: Think of alkenes like a popular party place with lots of activity (electrons)! Everyone (electrophiles) wants to join the party.

Electrophilic Addition Reactions: The Guest List 📜

  • 🎈 Electrophilic Addition of Halogens
    • Party Crashers: Diatomic halogens (X2).
    • Result: Halogens attach to the C=C bond, forming disubstituted halogenoalkanes (CnH2nX2).
    • Example: Ethene (C2H4) + Bromine water (Br2) = 1,2-dibromoethane (C2H4Br2).
    • Fun Fact!: This reaction helps test for unsaturated compounds. If bromine water loses its color, there are alkenes or alkynes dancing in your mix!
  • 🎈 Electrophilic Addition of Hydrogen Halides
    • Party Crashers: Hydrogen halides (HX).
    • Result: Hydrogen halide adds to C=C, forming a monosubstituted halogenoalkane (CnH2n+1X).
    • Example: but-2-ene (C4H8) + hydrogen bromide (HBr) = 2-bromobutane (C4H9Br).
  • 🎈 Electrophilic Addition of Water
    • Party Crashers: Water (H2O) in an acidic mix.
    • Result: Water adds to C=C, giving us an alcohol (CnH2n+1OH).
    • Example: hex-3-ene (C6H12) + water = hexan-3-ol (C6H13OH).

🤔 Interesting Thought: Ever wonder how chemists dream up ways to make new compounds? They use imagination, intuition, and reasoning! Just like using a recipe to bake a cake, they mix and match ingredients to create new treats.
