Question

Chlorination of benzene is not possible in the following
reaction :
(a) C₆H₆ + Cl₂ □(→┴FeCl₃ )
(b) C₆H₆ + HOCl □(→┴H⁺ )
(c) C₆H₆ + I - Cl □(→┴ZnCl₂ )
(d) C₆H₆ + Cl₂ □(→┴AlCl₃ )

Answer 1

Let us answer it

Explanation:

They have benzene ring C6 H6 (alternate 3 double bond with no benzene ring)

Chlorination of benzene

Substitution Reaction

 In this hydrogen is going to get substituted by some other group.

 C₆H₆ + Cl₂----> C₆H₅Cl + HCl

    Benzene   chlorine   benzyl chloride

 The Mechanism involved is electrophilic substitution mechanism  

This reaction involves halogen carrier that is : FeCl₃ , AlCl₃, ZnCl₂.

In the above question , (b) C₆H₆ + HOCl □(→┴H⁺ )  is incorrect that it is not possible in this case .
