How to pronounce“electrophiles”in English

We’ll talk about electrophiles for this reaction in a bit, but let’s start with the mechanism.

We're talking about electrophiles being the things that attack double bonds, in particular, ones where the electrophile is carbon, like the sigma-star of something

Alkenes are nucleophilic and can attack electrophiles, so the pi bond gets broken and two sigma bonds form.

And Lewis acids are also electrophiles.

One of the most important electrophiles we'll see throughout these videos are carbocations.

is formally quite different because you add electrophiles to alkenes.

Soft nucleophiles are more likely to attack soft electrophiles, and Hard nucleophiles are more likely to attack hard electrophiles For now, we're done with enols and enolates – but not with penicillin!
