1) Explain with halogens are deactivators, but ortho, para
directors, instead of m directors, in an EAS reaction.
2) Draw the energy diagrams for the first step of an
electrophilic aromatic substitution reactions of a monosubstituted
benzene, when the substituent is an electron-withdrawing group (E),
an electron-donating group (D), and a halogen (X),
respectively.
