🔥 Key Point: Electrophiles are electron-craving party crashers! They want to nab electrons from others.
Electrophiles Defined
- What? Electron-deficient species.
- What do they do? Love to accept a pair of electrons from an electron donor (known as a nucleophile) to make a cozy covalent bond.
Types of Electrophiles
- The Positively Charged Party Goers: Cations with a full positive charge. Imagine someone at a party who REALLY wants to be noticed!
- 🎈 Example: The methyl cation, +CH₃. It's like the person at the party wearing a neon shirt shouting, "Look at me!"
- The Neutral-but-not-so-neutral Guests: Neutral molecules having a 'partial positive charge' (δ+). These are the folks who act cool but still want attention.
- 🌩️ Reason for δ+: Presence of a super electronegative buddy causes a bond to get polarized. It's like when someone's super popular friend enters and suddenly they're in the spotlight too!
- 🎈 Example: Boron trifluoride, BF₃. The boron here feels left out and is thus open to a nucleophilic hug. Think of it like someone who's surrounded by three celebrities (F atoms) but feels left out in the conversations.
