For an electrophilic substitution reaction, the presence of a halogens

1.	For an electrophilic substitution reaction, the presence of a halogens atom in the benzene ring.
Answer» Deactivates the ring by inductive EFFECT Deactivates the ring by resonance Increases the charge density at ortho and PARA position relative to meta position by resonance Directs the incoming electrophilic to meta position by increasing the charge density relative to ortho and para position. Solution :Halogen atom present on benzene ring shows +R effect and increases electron density on ortho and para position and direct electrophilic on ortho and para POSITIONS. Halogen being more electronegative pulls the electron from benzene DUE to -I effect and DECREASES electron density but due to resonance the electron density on ortho and para positions is greater than meta position.
