How to convert toluene to meta bromo toluene

Answer 1

Answer:

pls mark brainless. .. :^)

Explanation:

Toluene + HNO3/H2SO4 --> p-nitrotoluene (para directed nitration)

p-nitrotoluene + Zn/HCl --> p-aminotoluene (changing NO2 to NH2 by reduction)

p-aminotoluene +Br2 --> bromination ortho to NH2

Remove NH2 via diazonium salt and decomposition with 1) HONO (which is NaNO2+HCl), 2) H3PO2 for the final product.
