arrange the following substituents in
decreasing order of ring activation for electrophilic aromatic
substitution:
-NHCOCH3, -CH3, -OCH3, -OH,
NO2, -H, Cl, NH2.
Sol: electron donating group activates the benzene ring to undergo electrophilic aromatic substitution. On the other hand electron withdrawing groups deactivate the ring as they withdraw electron density from the ring, make the ring less reactive for electrophilic attack.
Ring activation order for electrophilic aromatic substitution is:
-NH2 > -OH > - OCH3 > -NHCOCH3 > -CH3 > -H > -Cl > - NO2
arrange the following substituents in decreasing order of ring activation for electrophilic aromatic substitution: -NHCOCH3, -CH3,...
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. Activation of the ring towards...
