(a)
Interpretation:
The most likely sites of electrophilic
Concept introduction:
In electrophilic aromatic substitution reactions, certain substituents attached to a phenyl ring favor reaction at the ortho and para positions and are characterized as ortho/para directors. Other substituents favor reaction at the meta position and are called meta directors. Ortho/para directors increase the rate of electrophilic aromatic substitution and are called activating groups. Conversely, meta directors tend to slow the reaction rate and are called deactivating groups.
(b)
Interpretation:
The most likely sites of electrophilic aromatic substitution in the given molecule are to be predicted.
