Q41.Given below are two statements: Statement I : Nitration of benzene involves the following step - Statement II : Use of Lewis base promotes the electrophilic substitution of benzene. In the light of the above statements, choose the most appropriate answer from the options given below : JEE Main 2024 (05 Apr Shift 1) JEE Main Previous Year Paper (1) Statement I is correct but Statement II is incorrect(2) Statement I is incorrect but Statement II is correct (3) Both Statement I and Statement II are correct (4) Both Statement I and Statement II are incorrect
What This Question Tests
This question tests the understanding of the mechanism of electrophilic aromatic substitution, specifically nitration, and the general role of Lewis acids/bases in such reactions. Statement I correctly describes the formation of a sigma complex (carbocation intermediate), while Statement II incorrectly assigns a promoting role to Lewis bases in EAS reactions.
