Question

Which reaction is useful in exchange of halogen in alkyl chloride by iodide? (A) Wurtz reaction (B) Finkelstein reaction (C) Reimer-Tiemann reaction (D) Williamson synthesis

Tardigrade Admin · Accepted Answer

The reaction is useful in exchange of halogen in alkyl chloride by iodide is Finkelstein reaction. This reaction is used in preparation of alkyl iodide by the reaction of alkyl chloride, bromide with

N a I

in dry acetone

e.g.

C H_{3} C H_{2} B r + N a I Acetone Δ C H_{3} C H_{2} I + N a B r
