WebDec 5, 2024 · Ortho, Para Directing Group. If the relative yield of the ortho product and that of the para product are higher than that of the meta product, the substituent on the benzene ring in the monosubstituted benzene is called an ortho, para directing group. If the opposite is observed, the substituent is called a meta directing group. Web*CH3-Activating, ortho, para-directing *CF3- Deactivating, meta-directing Select all the statements that correctly describe the mechanism for the nitration of benzene. *In the first step, the pi system of the aromatic ring reacts with the nitronium ion. *In the second step, H2O acts as a base to remove H+ from the intermediate.
