We break down the step-by-step mechanism of halogenation of benzene using halogens (Cl₂, Br₂) in the presence of Lewis acid catalysts like FeCl₃ or AlCl₃.

These are reactions where a nucleophile, or a species rich in electrons, attacks an electrophilic carbon, usually bonded to a leaving group like a halide. As the nucleophile comes in, the leaving group gets kicked out, a molecular swap occurs! These reactions are key to building complex molecules and come in two main types: SN1 and SN2, each with its own mechanism and conditions.

These are highly reactive organomagnesium compounds that react with haloalkanes to form alkanes. Let's see how exactly the reaction proceeds and what makes it a powerful method for forming carbon–carbon bonds.
