Q
Nitrobenzene => Phenylamine Equation Type of reaction Conditions Reagents
A
-Nitrobenzene + 6[H] => Phenylamine +H2O Step 1. Nitro + [H] => phenylammonium salt Step 2. Phenyl salt + excess NaOH => phenylamine + 2H20 Type of reaction -Reduction reaction Conditions -reflux, [H] (tin and concentrated HCl) Reagents -Tin/Con HCl -excess NaOH

Q
Nitrobenzene => Bromonitrobenzene Equation Type of reaction Conditions Reagents
A
Equation Nitrobenzene + Br2 => bromonitrobenzene + HBr Type of reaction Bromination Conditions *Reaction is v. Slow at rt because the benzene ring in nitrobenzene is less susceptible to e- attack than benzene. so Halogen carrier catalyst is needed High temperature Reagents Br2
