Key Concept: What's a Radical? 🚀

A radical is a molecule that has an unpaired electron. Think of it as that one friend who doesn’t like to be tied down and dances solo at parties!

Drawing Electron Movement: The Art of Curly Arrows! 🖌

  • Double-Barbed Arrow (🡆🡆)
    • Shows the movement of a pair of electrons. Imagine a couple dancing hand-in-hand.
    • Real-world example: Passing a basketball (electron pair) to another player.
  • Fish Hook Arrow (🡆)
    • Represents the movement of just a single electron.
    • These are used when we're talking about radicals. Just like when someone does a solo dance move!
    • Real-world example: Juggling! When one ball (electron) is tossed, while the others remain in hand.

Important Pointers: a. Arrows start where the electrons are (electron-rich area). b. They point towards where the electrons want to go (electron-poor area).

Formation of Radicals: Breaking Up is Hard to Do! 🎭

Homolytic Fission: This is like a twin breakup! Here, a molecule splits in such a way that each atom gets one electron from the bond. Imagine a cookie being split, and each kid gets half. No fights! 😅

  • Example: Halogen radicals (like chlorine). When chlorine (Cl₂) breaks up, each Cl gets one electron.

  • Cl-Cl becomes Cl• + Cl• (The "•" represents the unpaired electron dancing solo!)
