The presence of a halogen on the benzene ring in a nitration reaction leads to:
| 1. | Direct nitro group to come at meta and deactivate the ring due to –I effect of halogen. |
| 2. | Direct nitro group to come at ortho and para position and deactivate the ring due to –I effect of halogen. |
| 3. | Direct nitro group to come at meta and activate the ring toward nitration reaction. |
| 4. | Nitration reaction does not take place due to deactivation caused by –I effect of halogen. |
