Electrophile attack where the electron density high.which shows +M or +I effects are ortho/para directing because they increase electron density at ortho and para +M $- \overset{• •}{N} H_{2}, - \overset{• •}{N} = O,$ ,,
The following groups are meta directing,, $- O M e, S O_{3} H$ They decreases electron density at ortho/para so, electrophile attack at meta position.
