34.2.1—Preparation of phenylamine via the nitration question 1

[Maximum number: 2]

Potassium iodide, KI, is used as a reagent in both inorganic and organic chemistry.

KI\quad \mathrm{KI} is used as a source of I−\mathrm{I}^{-}ions in organic synthesis.

One example of this is shown in the synthetic route in Fig. 1.1.
