These reactions are usually run in an organic solvent in order to bring the organic nitro compound into solution. What happen when- Nitrobenzene is treated with Sn/HCl? To a solution of the SM (70 g, 386 mmol) in AcOH (100 mL) and absolute EtOH (400 mL) was slowly added iron powder (40 g). Nitrobenzene undergoes electrophilic substitution at meta position. Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry. I'm skeptical about the mechanism, but it's worth putting it out there that in radical reactions C–H bonds are easier to cleave than O–H bonds due to their lower bond dissociation energies.
