Explain why a CH3 group directs electrophilic attack ortho and para to itself in substituted benzenes.
Explain why a CH3 group directs electrophilic attack ortho and para to itself in substituted benzenes.
An electron-donating inductive effect stabilizes the carbocation intermediate.
Why does an NH2 group direct electrophilic attack ortho and para to itself in substituted benzenes?
Why does an NH2 group direct electrophilic attack ortho and para to itself in substituted benzenes?
The NH2 group directs electrophilic attack ortho and para to itself because the carbocation intermediate has additional resonance stabilization.
What is the reason for meta attack occurring with the NO2 group (and all meta directors) in substituted benzenes?
What is the reason for meta attack occurring with the NO2 group (and all meta directors) in substituted benzenes?
Meta attack occurs because attack at the ortho and para position gives a destabilized carbocation intermediate.
