I keep getting “Markovnikov's rule” questions wrong in Hydrocarbons. What's the trap?
reversing it, except in the peroxide (anti-Markovnikov) effect.
The usual trap: reversing it, except in the peroxide (anti-Markovnikov) effect. How to avoid it: 'the rich get richer' — the H-rich carbon gains the H. Go back to the definition — when HX adds to an alkene, H attaches to the carbon that already has more hydrogens.
