1. For each of the following statements, indicate whether they are true of false. ⚫ a good way of thinking about meta directing groups is that they disfavour reaction at the ortho and para positions rather than promoting reaction at the meta position. ⚫ all activating (electron donating) groups are ortho/para directors and all deactivating (electron withdrawing) groups are meta directors. ⚫ diazotization of an amino group is very useful because the diazo group can be replaced with a number of other substituents. • benzene rings bearing meta directing groups cannot undergo Friedel-Crafts reactions. ⚫ when more than one substituent is present on a benzene ring, the directing effects of all substituents should be considered. ⚫ when substituents have conflicting directing effects, mixtures of products can form, but a strongly activating group can outweigh the effects of groups below it on the electron donation/withdrawal scale. ⚫ in a nucleophilic aromatic substitution reaction, the incoming nucleophile must be a weaker base than the halide ion that is being replaced.
