Question

The direct iodination of arenes ($Ar-H + I_2 \rightleftharpoons Ar-I + HI$) is heavily reversible. What explicit chemical reagent is fundamentally added to successfully drive the forward synthesis?

Correct answer: C. The byproduct is a potent reducing agent that natively cleaves the new bond. Adding an oxidizer like chemically consumes the by constantly oxidizing it back into molecular , strictly pushing the equilibrium forward.
