WebOrtho/para directors. Groups with unshared pairs of electrons, such as the amino group of aniline, are strongly activating and ortho/para-directing by resonance. Such activating groups donate those unshared electrons to the pi system, creating a negative charge on the ortho and para positions. These positions are thus the most reactive towards ... WebOrtho-para directing group: As discussed earlier, these groups direct the electrophilic attack on “ortho” and “para” positions. All activating groups are “ortho-para” directors, for example –NH 2, –NHR, –NHCOCH 3, –OCH 3 ,–CH 3, –C 2 H 5, etc. hand foot syndrome ctcae https://mp-logistics.net
