Concept / Reaction |
Key Point |
Example |
|
Basics |
Benzene prefers substitution (EAS) to retain aromaticity. |
Unlike alkenes, benzene avoids addition. |
|
Mechanism |
1. Electrophile generation → 2. Attack on ring (σ-complex) → 3. Deprotonation → aromaticity restored. |
Common electrophiles: NO₂⁺, SO₃, R⁺, X⁺ |
|
Nitration |
HNO₃ + H₂SO₄ → NO₂⁺ (electrophile) |
Benzene → Nitrobenzene |
|
Halogenation |
X₂ + FeX₃ → X⁺ |
Benzene → Halobenzene |
|
Sulfonation |
SO₃/H₂SO₄ → –SO₃H group |
Benzene → Benzenesulfonic acid |
|
Friedel–Crafts Alkylation |
RCl + AlCl₃ → R⁺ |
Benzene → Alkylbenzene |
|
Friedel–Crafts Acylation |
RCOCl + AlCl₃ → RCO⁺ |
Benzene → Acylbenzene |
|
Directing Effects |
–OH, –NH₂, –OCH₃, –R → Ortho/Para (activating). –NO₂, –COOH, –CN → Meta (deactivating). |
Predicts substitution position. |

Practice is key to preparing well for the EAS concept. Here are Electrophilic Aromatic Substitution NEET mindmap practice questions you should prepare well:
Predict the major product in substituted benzene reactions.
Determine the directing effect of a given substituent.
Solve nitration, halogenation, sulfonation, alkylation, and acylation problems.
Identify the position of substitution (ortho, meta, para) based on substituents.
Solve mechanism-based multiple-choice questions.
Mindmaps visually link mechanisms, reagents, and directing effects, making it easier to tackle both theory and numerical NEET questions.
Revising EAS effectively requires linking theory with patterns of aromatic reactivity. Here are some tips to revise the Electrophilic Aromatic Substitution concept with the help of the PW NEET mindmap:
Categorize reactions by type, i.e., Group nitration, halogenation, sulfonation, alkylation, and acylation separately with their electrophiles.
Use different colors for activating (ortho/para) and deactivating (meta) groups to recall substitution positions.
Memorize EAS by breaking it into three steps, i.e., electrophile generation then attack on the aromatic ring and then deprotonation to restore aromaticity.
Write down the unusual cases, like deactivated rings that undergo substitution slowly or poly-substitution patterns.
Instead of memorizing the concept, understand how electron-donating or withdrawing groups affect reactivity. This way you can predict products in new questions.
