Ch3 is ortho para directing
WebSome examples of directive influence of functional group in mono substituted benzene are explained below: Ortho-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 ... WebSince NO 2 is an electron withdrawing group, a glance at the resonance structures shows that the positive charge becomes concentrated at the ortho-para positions. Thus these positions are deactivated towards electrophilic aromatic substitution. Hence, NO 2 is a meta-director, as we all learned in organic chemistry.. Similarly, determine whether -CH …
