Vedclass · Answer

(D) When benzene reacts with an electrophile $E^{+}$,the electrophile attacks the $\pi$-electron system of the benzene ring to form a resonance-stabilized carbocation intermediate known as the $\sigma$-complex or arenium ion. In this intermediate,the carbon atom at the site of attack becomes $sp^3$ hybridized,bearing both the electrophile $E$ and the hydrogen atom $H$. The positive charge is delocalized over the remaining five carbon atoms of the ring,specifically at the ortho and para positions relative to the site of attack. Among the given options,the structure that correctly represents the delocalization of the positive charge in the arenium ion is option $(d)$.

In the reaction of benzene with an electrophile $E^{+}$,the structure of the intermediate $\sigma$-complex can be represented as
