Question

Can iodine be replaced by fluorine in finkelstein reaction

Answer 1

$\huge\frak\red{AnSwer}$

Finkelstein reaction: An SN2 reaction in which one halogen atom (the leaving group) is replaced by another halogen atom (the nucleophile). In this example of the Finkelstein reaction, 1-chloro-2-phenylethane (a primary alkyl halide) is treated with sodium iodide (the nucleophile) to produce 1-iodo-2-phenylethane.
