Question

Which of the following cannot be prepared by Sandmeyer’s reaction? (i) Chlorobenzene (ii) Bromobenzene (iii) Iodobenzene (iv) Fluorobenzene (A) (i) and (ii) (B) (ii) and (iii) (C) (iii) and (iv) (D) (i) and (iv)

Tardigrade Admin · Accepted Answer

* In case of (iii) Iodobenzene different reagents as KI used to obtain the product because it cannot be formed in presence of

C u (I)

(Iodine being less reactive than other halogens)

* And for (iv) Fluoro-benzene it cannot be formed by this reaction due to the high reactivity of Fluorine the reaction

b / wF

and benzene and rigorous and highly explosive.
The other 2 options (i) Chlorobenzene (ii) Bromobenzene can be formed by this reaction.
