OChem Cheat Code: 2nd Best Resonance Rule Predicts Nuc/Elec FAST!

Описание: Do you wish there was an OChem tip or trick to predict nucleophilic and electrophilic sites?: the 2nd best resonance contributor usually shows where a molecule is actually reactive. In this OChemNinja pro tip, you’ll use the “2nd best rule” to predict where molecules react - even if you’ve never seen the molecule before.

We’ll apply it to:
🧑‍🎓 Markovnikov addition to alkenes (why that regioselectivity happens)
🧑‍🎓 Protonated carbonyls (why they’re electrophilic at carbon)
🧑‍🎓 Diels-Alder regioselectivity
🧑‍🎓 Electrophilic aromatic substitution directing effects (ortho/para vs meta)
