Ortho
Meta
Para
Random
The position of the third substituent depends on the nature of the existing substituents; however, ortho and para positions are generally favored for activating groups.

Q
Q: In the presence of a strong electrophile, which position on a disubstituted benzene ring will a third substituent most likely attach?
Solution: The position of the third substituent depends on the nature of the existing substituents; however, ortho and para positions are generally favored for activating groups.
Steps: 5
Step 1: Identify the existing substituents on the disubstituted benzene ring.
Step 2: Determine if the existing substituents are activating or deactivating groups.
Step 3: If the existing substituents are activating groups (like -OH or -NH2), the third substituent will likely attach at the ortho or para positions.
Step 4: If the existing substituents are deactivating groups (like -NO2 or -CF3), the third substituent will likely attach at the meta position.
Step 5: Consider the strength of the electrophile; a strong electrophile will favor the positions that are more accessible.
