Question
What is the major organic product formed upon the mononitration of p-nitrotoluene using a mixture of concentrated $HNO_3$ and $H_2SO_4$?
Answer: A
π‘ Solution & Explanation
In p-nitrotoluene, the methyl group is an activating o/p director. The nitro group is a deactivating meta director. Both groups reinforce each other, directing the incoming electrophile to the exact same position (ortho to the methyl group), yielding 2,4-dinitrotoluene.
