Electrophilic Aromatic Substitution Reactions
Understand the mechanisms, types, and outcomes of electrophilic substitution in benzene, including nitration, halogenation, and Friedel-Crafts reactions.
Why this shows up in the exam
This is a core topic for both NEET and JEE, with frequent questions on mechanisms and products.
How NEET tests this
Practise it
These are real questions from past NEET papers that test this exact idea.
Some meta-directing substituents in aromatic substitution are given. Which one is most deactivating?
Push further
More challenging24 harder questions built from the past papers above — a step up in difficulty, with distractors designed so you can't get there by elimination. Written and checked by our reviewers, not from a real paper.
In the nitration of chlorobenzene, what is the primary role of concentrated sulfuric acid?
