  4. Bottles containing PhI and PhCH 2 I lost their original labels. They were labelled as (A) and (B) for testing. (A) and (B) were separately taken in test tubes and boiled with NaOH solutions. The end solution in each tube was made acidic with dilute HNO 3 and some AgNO 3 solution was added. Substance (B) gave a yellow precipitate. Which of the following statements is true for this experiment?

Q. Bottles containing $PhI$ and $PhCH _2 I$ lost their original labels. They were labelled as (A) and (B) for testing. (A) and (B) were separately taken in test tubes and boiled with $NaOH$ solutions. The end solution in each tube was made acidic with dilute $HNO _3$ and some $AgNO _3$ solution was added. Substance (B) gave a yellow precipitate. Which of the following statements is true for this experiment?

Haloalkanes and Haloarenes

Solution:

Aryl halide due to resonance does not give test for halide ion, whereas benzyl halides give due to the formation of benzyl $C ^{\oplus}$ which gives benzyl alcohol and $I ^{\ominus}$
$Ph I + Aq . NOH \rightarrow$ No reaction
