Sort the following compounds by their reactivity toward electrophilic aromatic substitution.
Revelant knowledge
Electrophilic aromatic substitution is an organic reaction in which an hydrogen atom or functional group in one aromatic substance is exchanged for another functional group that can be the case with an electrophile
This problem was solved by the concept of EAS (electrophilic aromatic substitution). The electrophilic aromatic substitution is an organic reaction, and is defined by the substitution of an atom linked to the aromatic rings (usually the benzene) with an electrophile.
In the EAS, the aromatic ring (usually benzene) acts as a nucleophile, replacing the atom that is substituting it with an electrophile. This implies that benzene will give electrons away from its ring. This means that benzene is less reactive within the EAS when electron-drawing group (deactivating group) are attached to it. However the ring becomes more active towards EAS when the electron-donating group gets associated with it.
The functional group in toluene and aniline causes the ring to move towards EAS. On the other hand the functional group bonded to the fluorobenzene, the nitrobenzene, and acetophenone disengages the ring from the EAS.
Answer: You can sort the compounds by their reaction to electrophilic aromatic substitution in this order:
