There are two main effects of substituents. The substituent will affect the rate of reaction (aka reactivity) of the ring, and it will also affect the position of attack (called “directing effects”) on the ring by the incoming electrophile. Thus we need to answer the following questions: Does the substituent activate or deactivate the aromatic ring?
