Detailed Solution

image Key Points:

  • Benzene + Br2/Fe = electrophilic aromatic substitution (halogenation)
  • Aryl halides + Mg = aryl Grignard reagent
  • Grignard + proton donor (ROH, \ceH2O\ce{H_2O}) = alkane (protonation of C-Mg)
  • \ceCH3\ce{CH_3}OH acts as proton source for Grignard: \ceRMgX+R′OH−>RH+R′OMgX\ce{RMgX + R'OH -> RH + R'OMgX}
