Bottles containing `C_(6)H_(5)I` and `C_(6)H_(5)-CH_(2)I` lost their original lables. They were labelled A and B for festing. A and B were separately taken in a test tube and boiled with `NaOH` solution. The end solution in each tube was made acidic with dilute `HNO_(3)` and then some `AgNO_(3)` solution was added. Substance B gave a yellow precipitate. Which one of the following statements is true for this experiment.

Options

A. A and `C_6H_5CH_2I`
B. B and `C_6H_5I`
C. Addition of `HNO_3` was unnecessary
D. A and `C_6H_5I`

Answer

D

Explanation

`C_6H_5I` will not respond to silver nitrate test because C-I bond has a partial double character.
