Question

In the detailed multi-step mechanistic view of electrophilic aromatic substitution, an electrophile ($E^+$) interacts with benzene to form various complexes. Which of the following statements correctly describe these initial interactions and complexes?

Prashant Kotian · Accepted Answer

Correct answer: A,B,D. A -complex forms via a weak interaction between the electrophile and the -cloud. In the -complex, a distinct covalent bond forms, breaking aromaticity and creating an carbon. The -complex sits in an energy valley (a true intermediate). Aromaticity is lost, not restored, when moving from the -complex to the -complex.
