🧠 The Substituent Tug-of-War
The stability of a carbocation on a benzene ring is determined by how well the substituents can donate or withdraw electrons. The  group is a "black hole" for electrons (strong  and  effect). Placing a positive charge near it is a recipe for instability.

🗺️ The Stability Mapping
1. Deactivating Effect: The  group pulls electron density away from the ring, making the whole system electron-deficient.
2. Ortho/Para Attacks: If the positive charge lands on the carbon
