What happens to the following intermediate of aromatic electrophilic substitutio

Question

What happens to the following intermediate of aromatic electrophilic substitution on next step of the reaction? It turns to the product of addition, because it loses aromaticity It turns to the product of addition, because it gains aromaticity It turns to the product of substitution, because it loses aromaticity It turns to the substitution, because it gains aromaticity It turns to the product of substitution, because it loses antiaromaticity How would you classify acid-catalyzed hydration of alkenes? addition elimination substitution bromination combustion "The following intermediate is aromatic, because it has four electrons from C=C bonds and two electrons from the N=O bond in conjugation, so it satisfies Huckel's rule" What is your opinion about this statement? True, because the intermediate has 6 electrons False, because the intermediate has 6 electrons in cyclic conjugation False, because there is no cyclic conjugation True, because there is no cyclic conjugation False, because the methyl and nitro-groups are in the ortho-position with respect to one another Which of the following reactions is acylation?

Explanation / Answer

4) During electrophilic aromatic substituion, an electrophile attacks the pi bond of the benzene nuclus forming an arenium ion intermediate. The formation of arenium ion intermediate leads to the loss of aromaticity of the benzene nucleus and the intermediate is high energetic aswell. As a reult of which in the subsequent step the intermediate lose a proton and the compoud restore its aromaticity.

Ans- (D) i.e.- It turns to the product of substitution, because it regains its aromaticity
