Substituents on an aromatic ring can have several effects on
electrophilic aromatic substitution reactions. Substituents can
activate or deactivate the ring to substitution, donate or withdraw
electrons inductively, donate or withdraw electrons through
resonance, and direct substitution either to the ortho/para or to
the meta positions. From the following lists, select the
substituents that have the indicated property. The substituents are
written as -XY, where X is the atom directly bound to the aromatic
ring.
