Question

Among the following the reaction that proceeds through an electrophilic substitution is

• A.
• B.
• C.
• D.

Answer 1

The correct option is D \( \sqrt{\square}+ Cl _{2} \stackrel{ AlCl _{3}}{\longrightarrow} \longrightarrow Cl + HCl \)

$Cl-Cl+AlC{l}_3\to C{l}^{\oplus }\text{[Electrophile]}+AlC{l}_4^{-}$
Here $C{l}^{+}$ act as an electrophile.
\( Cl - Cl + AlCl _{3} \longrightarrow Cl ^{+} \longrightarrow Cl ^{+}+ AlCl \) \( \oplus \) \( H ^{+}+ \) \( \longleftrightarrow \)
