Concept explainers
For each N-substituted benzene, predict whether the compound reacts faster than, slower than, or at a similar rate to benzene in electrophilic
a. b. c. d.
(a)
Interpretation: The given compound reacts faster than, slower than, or at equal rate to benzene in electrophilic aromatic substitution is to be predicted and the major product(s) formed by the reaction between given compound and general electrophile
Concept introduction: The replacement or substitution of one functional group with another different functional group in any chemical reaction is termed as substitution reaction. The electron deficient chemical species that contains positive charge are known as electrophile. In electrophilic aromatic substitution reaction, electrophile takes the position of hydrogen atom by attacking the electron rich carbon atom of benzene.
Answer to Problem 18.49P
The given compound reacts faster in electrophilic substitution reaction than benzene ring. The major product formed by the reaction between given compound and general electrophile
Explanation of Solution
The electron donating groups or activating groups make benzene ring more electron rich, as a result the compound reacts faster in electrophilic substitution reaction than benzene ring. On the other hand, the electron withdrawing groups or deactivating groups make benzene ring less electron rich; as a result the compound reacts slower in electrophilic substitution reaction than benzene ring.
In the given compound, benzene ring is attached to
The activating groups are ortho, para directing whereas the deactivating groups are meta directing. The major product formed by the reaction between given compound and general electrophile
