Скачать или смотреть Carbocation Stability Made Easy: Hyperconjugation Explained

Why are some carbocations rock solid (well… relatively) and others barely exist? In this quick tutorial, I’ll show you two clean ways to explain the stability trend - so you can rank carbocations fast and know when the usual rule breaks.

You’ll learn:
👍 How alkyl groups donate electron density (+I) to stabilize a positive charge
👍 What hyperconjugation actually is (σ C–H/C–C → empty p orbital)
👍 The orbital picture: sp², trigonal planar, empty p
👍 Why a tertiary carbocation is most stable and a methyl carbocation least stable
👍 The big exception: resonance-stabilized (allylic/benzylic) carbocations
👍 How this shows up in SN1, rearrangements (hydride/methyl shifts), and exam traps
