Q15Multiple correct
For an electrophilic substitution reaction, the presence of a halogen atom in the benzene ring _______.
- (i)deactivates the ring by inductive effect
- (ii)deactivates the ring by resonance
- (iii)increases the charge density at ortho and para position relative to meta position by resonance
- (iv)directs the incoming electrophile to meta position by increasing the charge density relative to ortho and para position.
Show answer
(i) deactivates the ring by inductive effect
(iii) increases the charge density at ortho and para position relative to meta position by resonance
