Why is Fe scrap with HCl preferred to reduce nitro compounds?
ANo side products form
BExcess HCl is needed
CFeCl2 regenerates HCl
DIron is the best reductant
Answer & Solution
Correct answer: C. FeCl2 regenerates HCl
FeCl2 hydrolyses to release HCl, so only a small amount of acid is needed to start the reduction.
