Canvas Classes · Accepted Answer

Step 1: Analyzing EAS Reactivity
Electrophilic Aromatic Substitution (EAS) reactivity is increased by electron-donating groups and decreased by electron-withdrawing groups.
- Toluene (B):  is activating via  and hyperconjugation.
- Benzene (A): The reference compound.
- Chlorobenzene (C):  is deactivating due to its strong  effect (which outweighs ).
- Nitrobenzene (D):  is strongly deactivating via  and  effects.

Step 2: Conclusion
The correct order of reactivity is: B  A  C  D.
