Chemistry - Aromatic Hydrocarbon Question with Solution | TestHub
Benzene and other aromatic rings have tendency to undergo electrophilic aromatic substitution reactions and do not undergo electrophilic addition reactions like alkenes and alkynes.
Monosubstituted benzenes undergo substitution reactions either faster or slower than benzene depending on the fact that whether the group is electron donating or electron withdrawing, respectively. The directive influence of a group is determined by the fact that the arenium formed by the attack of electrophile on a particular position is more stable than the arenium ion formed by attacking other positions.
Side chain oxidation of benzene gives benzoic acid irrespective of the length or nature of the side chain .
In the given reaction
the probable product would be
Options:
Answer:
Solution:
The benzene ring attached to N−atom of −NH−CO− is activated whereas the other benzene attached to −CO− is deactivated. Therefore, substitution takes place at the para position of activated benzene.
