Benzene and Its Derivatives - How Do Existing Substituents on Benzene Affect Electrophilic Aromatic Substitution?
4 important questions on Benzene and Its Derivatives - How Do Existing Substituents on Benzene Affect Electrophilic Aromatic Substitution?
What effect can substituents have on the further eletrophilic aromatic substitution of benzene?
2. Substituents can affect the rate of substitution of the new group.
What is an ortho-para director?
What generalizations about substituent groups to benzene can be made?
2. All ortho-para directing substituents are activating, except for halogens.
3. All meta directing groups carry a full or partial positive charge on the atom directly bonded to the benzene ring.
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
Why are halogens deactivating?
2. A halogen can stabilize the cation by delocalizing its positive charge.
The question on the page originate from the summary of the following study material:
