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.

Explanation / Answer

activation of the ring towards substitution: -Br, -NHCOCH3, CH3

withdrawl of electrons through resonance: -NO2 and SO3H

ortho/para-directed substitution; -CH3, -Br, -OH
