Difference between Activating and Deactivating Groups || Easy Explanation || Aromatic Hydrocarbons

In Electrophilic Aromatic Substitution (EAS) reactions, substituents already present on the benzene ring play an important role in deciding the reactivity of the ring.
These substituents are broadly classified into Activating groups and Deactivating groups.

In this video, you will clearly understand the difference between activating and deactivating groups with easy explanation, examples, and effects that are very important for BSc 1st Year Organic Chemistry.

📘 Topics Covered

✔ What are activating groups?
✔ What are deactivating groups?
✔ Effect of substituents on benzene reactivity
✔ +M, –M, +I and –I effects
✔ Why activating groups increase rate of reaction
✔ Why deactivating groups decrease rate of reaction
✔ Examples of activating groups (–OH, –NH₂, –CH₃ etc.)
✔ Examples of deactivating groups (–NO₂, –COOH, –SO₃H etc.)
✔ Relation with ortho/para and meta directing nature
✔ Difference table for exam writing

🧠 Easy Explanation (Exam Ready)

• Activating groups donate electron density to the benzene ring by +M or +I effect, making the ring more reactive towards electrophilic attack.
• Deactivating groups withdraw electron density from the benzene ring by –M or –I effect, making the ring less reactive towards electrophiles.
