Hard Practice — Multi-step Reasoning & Structure Deduction
These questions chain ideas: ozonolysis / test deductions (work backwards from the products to the structure), regiochemistry with carbocation stability, directing-effect reasoning and reaction sequences.
- Markovnikov (via the more stable carbocation) vs peroxide effect (HBr only, radical, anti-Markovnikov).
- Ozonolysis cleaves C=C into two carbonyls; Baeyer's / bromine water confirm unsaturation.
- Aromatic reactivity: activators (o/p, faster) vs deactivators (m, slower).
